be generated for a single object file on AIX, automatically switch to
an indirection scheme that uses much less TOC entries, but is slower to
access global variables
* manually merged infrastructure for target-specific code generation
switches from JVM branch (-CTxxx switches)
* -CTsmalltoc switch for AIX that forces the indirection scheme for TOC
entries from the start in case the automatic one does not conserve
a sufficient amount (or in case you bump up against the global TOC
entries limit during linking)
git-svn-id: trunk@20963 -
based on the actual target platform rather than always on the host
platform
* on Unix, use single rather than double quotes for quoting, so it also
properly handles $, ! and `, which keep their special meaning when
appearing in scripts inside double quotes
* since sysutils.executeprocess() can only deal with double-quoted
strings in parameters, re-quote parameters on Unix when they turn
out not to be for scripts but for direct execution (which is most
of the time, but unfortunately doing the reverse is not possible
because parameters used in scripts sometimes contain script-specific
code that must not be quoted, such as `cat link.res`)
-> always use cfileutl.RequotedExecuteProcess() rather than
sysutils.ExecuteProcess() in the compiler (added a bunch of dummy
ExecuteProcess string constants to common units to prevent accidental
usage)
git-svn-id: branches/jvmbackend@20901 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line

to low addresses in case the target cpu/OS does not support this (enabled
for reads on AIX/PPC because on AIX the first 16KB are readable)
git-svn-id: trunk@20832 -
+ -CTcompactintarrayinit command line option to change the code generation
for typed array of some kind of integer-type initialization so that it
takes up less space in the bytecode (because the bytecode for all
routines, including the class initialization code that contains the
typed constant init code, is limited 64kb, large array or multiple
array constants could fairly easily bump into that limit)

* For now placed actual processing of unwind info under {$ifdef TEST_WIN64_UNWIND}, because in the current state it doesn't add much value.
git-svn-id: trunk@19200 -
- return default compiler codepage to 8859-1
- emit ansistring constants in CP_NONE by default
- add new modeswitch systemcodepage which sets default compiler codepage to system and emits ansistring constants with systemcodepage as delphi do
- add new mode DelphiUnicode with has the same switches as delphi mode + systemcodepage switch. Later it will also have string = unicodestring by default.
git-svn-id: trunk@19165 -
var-parameters on the JVM target for changes to the value passed
as var-parameter during the function call (because they are handled
via copy-in/copy-out, this may indicate unexpected bahviour later on).
out-parameters are checked in the same way, except if the out-parameter
is a local variable because then reading it before the call may result
in a bytecode verification error (since the variable may not yet be
initialized)
git-svn-id: branches/jvmbackend@19153 -
+ support parsing of strings with code page specification
+ added encoding and elementsize field to ansi- and unicodestring records
+ some basic rtl support routines for encoding aware strings

unicodestring = java.lang.String. The reason this was the default in
the past is that this was the first string type that was implemented,
and without it being the default most code involving string operations
would fail. Now the default strings types are the same as for other
targets
+ new {$modeswitch unicodestrings} directive, that when activated
*together* with {$h+},
1) changes char into an alias for widechar
2) changes string into an alias for unicodestring
3) changes the preferred string evaluation type (in case of uncertainty)
to unicodestring
{$modeswitch unicodestrings} with {$h-} does not change anything at all
regarding the string type (it still changes the char type)
+ new uuchar unit that redefines char as widechar, and which is automatically
included by the compiler if {$modeswitch unicodestrings} is enabled

is unicodestring (does *not* change the type of "char" to "unicodechar"
(yet)). Not yet (un)selectable via a directive.
+ systems_default_unicodestring set containing systems on which the
default string type is unicodestring
git-svn-id: branches/jvmbackend@18415 -
via {$modeswitch finalfields} (on by default on the JVM target). The
meaning is the same as in Java: a final (class) field can only be set
in a (class) constructor of the class it's defined in, and can only be
written once there (and *must* be set there). They are currently only
supported for external classes since that basically turns them into
constants, since for non-external classes we need full dataflow analysis
o refactored pdecobj.parse_object_members() a bit in the process to reduce
the amount of repetition (which would have been further increased for
the support for final fields)
o made error message about "wrong use of absolute" for fields etc generic,
so it gives a proper error depending on which token was used (it had
to be made generic for "final" support, but already was used for other
things that were wrongly reported as "absolute" misusages)
git-svn-id: branches/jvmbackend@18398 -
+ it_interfacejava type (not explicitly selectable via -SI nor
{$interfaces xxx}, but default for jvm target)
* disable it_interfacecom/corba for jvm target
+ init_settings for jvm that select it_interfacejava as default interface
type
+ default_class_type constant (in symconst) that is odt_javaclass for the jvm
target and odt_class for other targets (used to determine the meaning of
"type x = class" declarations)
git-svn-id: branches/jvmbackend@18286 -
by the JVM register allocator to store register values in, instead of
tt_noreuse (because almost all registers have to be mapped to temps,
no reusing these temps will blow up the stack frame a lot)
* documented the meaning of the tt_* values
* temp growing direction for jvm is also positive
git-svn-id: branches/jvmbackend@18284 -
* globtype.pas:
tmsgstate updated (ms_on/off/error_global variants added).
ms_local_mask, ms_global_mask : new constants.
tmessagestaterecord: new record, use to list chains
of local changes to warnings by $WARN directive.
pmessagestaterecord: new pointer to tmessagestaterecord.
* globals.pas:
tsettings record:
new field: pmessage of type pmessagestaterecord;
* cmsgs.pas:
TMessage class:
New method: ResetStates; Called on unit parsing changes
New Method: SetVerbosity(nr:longint;newstate:tmsgstate):boolean;
Remember global state in
replacing ClearVerbosity method.
New boolean field: has_local_changes
set if a call to SetVerbosity makes a local change that must be
reset when changing unit.
* verbose.pas:
New functions/procedures:
function SetMessageVerbosity(v:longint;state:tmsgstate):boolean;
for changes caused by $WARN or option
procedure RestoreLocalVerbosity(pstate : pmessagestaterecord);
procedure FreeLocalVerbosity(var fstate : pmessagestaterecord);

Implement recordpendingmessagestate
flushpendingswitchesstate: Handle new pmessage field of
current_settings record.
* parser.pas:
Handle pmessage field of current_settings.
* scandir.pas:
Handle also integer constants in $WARN.

+ support for nested procedural variables:
o activate using {$modeswitch nestedprocvars} (compatible with all
regular syntax modes, enabled by default for MacPas mode)
o activating this mode switch changes the way the frame pointer is
passed to nested routines into the same way that Delphi uses (always
passed via the stack, and if necessary removed from the stack by
the caller) -- Todo: possibly also allow using this parameter
passing convention without enabling nested procvars, maybe even
by default in Delphi mode, see mantis #9432
o both global and nested routines can be passed to/assigned to a
nested procvar (and called via them). Note that converting global
*procvars* to nested procvars is intentionally not supported, so
that this functionality can also be implemented via compile-time
generated trampolines if necessary (e.g. for LLVM or CIL backends
as long as they don't support the aforementioned parameter passing
convention)
o a nested procvar can both be declared using a Mac/ISO Pascal style
"inline" type declaration as a parameter type, or as a stand-alone
type (in the latter case, add "is nested" at the end in analogy to
"of object" for method pointers -- note that using variables of
such a type is dangerous, because if you call them once the enclosing
stack frame no longer exists on the stack, the results are
undefined; this is however allowed for Metaware Pascal compatibility)
git-svn-id: trunk@15694 -
+ {$modeswitch objectivec2}, which is required before you can use
Objective-C 2.0 features (such as the above). It automatically
also implies {$modeswitch objectivec1}
+ genloadfield() helper to load a field of a node representing
a record/object/class
git-svn-id: trunk@15460 -
- add own symbol table for enumeration to store enumeration elements
- reimplement enumeration member traverse using symbol table instead of firstenum/nextenum - that members are removed
- implement TEnum.Element access syntax - element is searched in the enumeration symtable in this case instead of global/local symtables
- implement {$SCOPEDENUM ON/OFF} local switch
+ tests

properties/behaviour of the equivalent of Extended in C (i.e., to
"long double" on i386 and x86_64 platforms that support a 10 byte

- complete $WARN switch parsing and add a stab to change message state
- reimplement way of message hiding by -vm switch (by Dmitry Boyarintsev)
(note: $WARN switch does not work at the moment since state handling is not yet implemented)
git-svn-id: trunk@14809 -
info with the classname, like is done for Stabs. Not done by default
because otherwise once calling methods from the debugger is implemented,
this would require typing classinstance.classname__methodname
git-svn-id: trunk@14337 -
(and hence those directories were interpreted as source files themselves)
+ added -gostabsabsincludes option to make the compiler store absolute
paths to include files in Stabs debugging information (since no
search paths are used). This is not the default because it breaks
when only the base path of an entire source tree changes (relative
paths, which are the previous behaviour and the current default,
work fine, but the absolute paths don't anymore; this can happen
with shared network drives, and possibly with distros shipping
external .dbg files)
git-svn-id: trunk@12933 -
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
can be used cumulatively with every syntax mode. Note that a {$mode xxx}
statement resets all mode switches as well, so you cannot use the
-Mobjectivec1 variant if you have such a statement in a unit. This
modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
as the backend support is not yet implemented for other platforms.
+ implemented selector() statement that can be used to create an Objective-C
selector for the message with the specified *constant* name (in the future,
it will also work for Objective-C method identifiers)
+ added SEL type to the system unit (the selector() statement returns it)
+ added all Objective-C segments to the assembler writers
+ (currently mostly dummy) objc1 unit that is automatically included if the
{$modeswitch objectivec1} statement is used
+ some tests for the selector() statement
