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 -
support the stabx as understood by gdb, which is a mixture of regular
stabs and stabx (e.g., class/object definitions are completely different
in real stabx). This means that gdb can be used to debug aix programs,
but the native dbx will complain about lots of debug information
constructs

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)

of the AVR-specific ifdef'ed variant
o since the only special character we use in mangled names on all platforms
is $, added a new field to tasminfo called "dollarsign" that holds the
character $'s should be replaced with (if it doesn't have to be replaced,
leave it at $)

be used outside the code generator
* renamed tabstractprocdef.requiredargarea into callerargareasize,
and also added calleeargareasize field; added init_paraloc_info(side)
method to init the parameter locations and init those size fields and
replaced all "if not procdef.has_paraloc_info then ..." blocks with
procdef.init_paraloc_info(callersize)"
* moved detection of stack tainting parameters from psub to
symdef/tabstractprocdef
+ added tcallparanode.contains_stack_tainting_call(), which detects
whether a parameter contains a call that makes use of stack paramters
* record for each parameter whether or not any following parameter
contains a call with stack parameters; if not, in case the current
parameter itself is a stack parameter immediately place it in its
final location also for use_fixed_stack platforms rather than
first putting it in a temporary location (part of mantis #17442)
* on use_fixed_stack platforms, always first evaluate parameters
containing a stack tainting call, since those force any preceding
stack parameters of the current call to be stored in a temp location
and copied to the final location afterwards
git-svn-id: trunk@16050 -
+ 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 -
(the ABIs that prescribe special treatment for aggregates with one
scalar element don't either, since a "union containing a single scalar"
is not the same as a scalar)
* fixed passing record with a single float field on PowerPC/AIX abi's
* several changes to cgobj and ncgutil to correctly deal with transfering
such records between integer and floating point registers
git-svn-id: trunk@15416 -
represent complex locations (required for full x86-64 ABI support,
which is not yet implemented) -> lots of special result handling
code has been removed and replaced by the parameter handling
routines
+ added support for composite parameters (and hence function
results) to tcg.a_load_ref_cgpara() (so it can be used for
handling, e.g., 64 bit parameters on 32 bit platforms)
* the above fixed writing past the end of allocated memory when
handling records returned in registers on x86-64 whose size is
not a multiple of 8 bytes (mantis #16357)
- removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
as they are now handled correctly by the generic version
* moved the responsibility of allocating tcgpara cpu registers
(using paramanager.allocparaloc()) from the callers of
cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
themselves (so the register allocation can be done efficiently
when dealing with function results)
* for the above, renamed paramanager.alloc/freeparaloc() to
paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
to allocate individual pcgparalocations instead
* fixed the register size of SSE2 function result registers for
x86-64 (when used for floating point), which results in removing
a few superfluous "movs? %xmm0,%xmm0" instructions
* fixed compilation of paramanagers of avr, m68k and mips after r13695
and also updated them for these new changes
git-svn-id: trunk@15350 -
mark_NoLineinfoEnd
* add "no line info" markers for try/except and try/finally internal cleanup
code, so the debugger doesn't jump back and forth between the end and start
of exception blocks when you arrive at the end
* honour "no line info" markers in dbgdwarf.pas

* the objc unit links against the Foundation instead of against the Cocoa
framework, and inludes an interface to either the fragile or non-fragile
obj-c run time depending on the target platform
+ support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
are now also supported for the objectivec1 modeswitch
+ support for private_extern symbol bindings, required for the above
* mark objcclasses that are declared in the implementation section of a
unit as "hidden" (not sure what the effect is, since the Objective-C
runtime does not seem to do anything with this flag)
* enabled all obj-c tests for the newly supported platforms
git-svn-id: branches/objc@13763 -
forced to something else by the compiler (internal rtl functions etc),
necessary for the objc branch
* fixed adding all used function result registers to the list of
registers that may need to be saved before a function call
git-svn-id: trunk@13695 -
depend on that (and correct a number of cases where this was wrong)
* set the correct subreg type for xmm x86_64 parameter registers
(resolved mantis #14067)
git-svn-id: trunk@13410 -
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
git-svn-id: trunk@12870 -
alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)
git-svn-id: trunk@12719 -
+ Forced PathConv argument to ShortString. Made a note about implementing AnsiString-aware PathConv later.
+ Made code to use the unified PathConv import (named Unix2AmigaPath(), which explains its functionality better).
+ The above changes fixed various compiler crashes in TAsmScriptAmiga, caused by invoking PathConv with AnsiString arguments, while it only supports ShortString
git-svn-id: trunk@12485 -
because it is faster and more system conform on Amigaish systems (like MorphOS, AmigaOS4 and more) than GNU AS.
btw, these are the same reasons why FPC/MOS use VLink instead of GNU LD...
+ simple programs compile with it, compiler doesn't work yet. (i'm in touch with VASM maintainer to address some issues)
+ TODO: add a command line switch to turn it on from command line.
