the generation of the procdef's asmsymbols
o also removed unnecessary definition of procdef alias symbols for Darwin
(they are already defined in ncgutil.alloc_proc_symbol)
git-svn-id: trunk@42341 -
* using this the TypInfo unit can navigate interface methods and VMT method parameters much more quickly as the latter have a constant size now
git-svn-id: trunk@39686 -
Note: I'm not yet really happy with both AT_DATA_FORCEINDIRECT and AT_DATA_NOINDIRECT; maybe I should replace them with flags or something like that...
git-svn-id: trunk@35366 -
it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler
git-svn-id: trunk@34250 -
symbol is defined
o removed all places where AB_INDIRECT symbols were explicitly generated
o only generate AB_INDIRECT symbols for AT_DATA on systems_indirect_var_imports
o for some symbols an indirect symbol is always required (because they are
dereferenced by code in RTL units) -> use new AT_DATA_FORCEINDIRECT type
git-svn-id: trunk@34165 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary
git-svn-id: trunk@34164 -
symconst.pas:
+ new constant suffix_indirect which will be used to denote indirect symbols
aasmbase.pas:
* TAsmsymbind: extend by AB_INDIRECT (which is used to define an indirect symbol) and AB_EXTERNAL_INDIRECT (which is used when an unknown indirect symbol is requested)
* asmsymbindname: adjust for TAsmsymbind changes
+ new constant asmsymbindindirect which is a set of both indirect asm symbol binds
aasmdata.pas, TAsmData:
* DefineAsmSymbolByClass: adjust to correctly declare an indirect symbol (with suffix_indirect) if one of the indirect asm symbol binds is used
* RefAsmSymbol: extend by a boolean parameter which is used to request an indirect symbol (usually AB_EXTERNAL_INDIRECT instead of AB_EXTERNAL)

(object-local, but not starting with (.)L, so they're still treated as
the start of a subsection by Darwin's linker when dead-stripping)
+ tasmdata.getstaticdatalabel() that uses the above

A more radical approach is to remove them altogether. Tested with i386-win32 (the oldest peephole optimizer), mips-linux (the newest one) and arm-linux (the most complex one) targets. The fallout was limited to two minor issues fixed in r28629 and r28708, respectively.

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 -
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
git-svn-id: branches/jvmbackend@20887 -
- add TTagHashSet class descendant of THashSet with an ability to has also a LongWord value together with key
- change TAsmData.ConstPools[] to be an indexed property to properly initialize ConstPool class, remove pool initialization from all other units
- add ansistring constants to pool together with their encoding to distinct the same text constants with different codepage
+ test
git-svn-id: trunk@19261 -
mangled name handling ansistring rather than pshortstring based (required
for JVM target; little effect on speed, some extra memory usage)
git-svn-id: branches/jvmbackend@18597 -
systems when smart linking and PIC are on, because on Darwin this
breaks smart linking and it's not necessary there (probably should be
disabled completely and the problem should be solved in another way)
(mantis #17593)
git-svn-id: trunk@16122 -
as needed, instead of once when initialising the list (currently nothing
else is added to that asmlist so it was safe, but it was not robust)
git-svn-id: trunk@15742 -
- sort of reverted r14134, which is no longer required after the above
change (new_section() inserts the alignment itself)
* made the tai_section.create() constructor private so it cannot be
called directly anymore
git-svn-id: trunk@15482 -
* constant widestrings must be allocated and copied at program start up through an api call else they couldn't be passed between progam/dlls
