Note: such files can be linked GNU ld only starting from 2.25; then again the older versions would fail anyway as they'd complain about a too high section count...

Note: the field names of tcoffbigobjheader and coffbigobjsymbol are inspired from the field names of the structs declared in LLVM

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
Switched codegeneration of VFPv2 and VFPv3 to use UAL mnemonics and syntax.
Updated VFP code in RTL to use UAL syntax too.
Added preliminary ELF support for ARM.
Added support for linking of WinCE COFF files. Should work for with a standard ARMv4-I target.

the value set by -Ch or the second parameter to the $M directive). This is
equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
has at least this amount of heap space available (otherwise DOS will show a
'not enough memory' error and will refuse to load the program).

itself (instead of having a fixed 16k stack in the startup code). This allows
setting the stack size in these models with the -Cs option.
git-svn-id: trunk@27820 -
* Dropped TObjInput.newObjData method. Instead, TObjData instances are created directly in ReadObjData, this gives possibility to create a different type of TObjData based on file header.
- Dropped TObjInput destructor, it does nothing except calling inherited.
git-svn-id: trunk@23118 -
* For Win32 and Win64 targets made sec_rodata read-only, too (for these targets it doesn't matter if read-only section contains relocations).
git-svn-id: trunk@23025 -
* TExeOutput.FixupSymbols:
+ Collect AT_GNU_IFUNC symbols in IndirectObjSymbols list for further processing by ELF back-end.
* Do not overwrite bind and size while fixing AB_COMMON symbols, this removes need in storing symbol size in every relocation and dedicated handling of oso_common section.
* Remove symbols with objsection<>nil from lists, so calling FixupSymbols several times skips already processed symbols.
git-svn-id: trunk@22393 -
+ Added TObjSection.WriteBytes method that writes just a string (without zero byte).
* ogelf.pas: Fixed st_value of COMMON symbols, it must contain required symbol alignment.
+ ogelf.pas: Some more definitions.
git-svn-id: trunk@22332 -
* Optimized COFF importing code using the new method.
- Don't create .text sections for imported variables.
- Don't create .idata$6 sections for imports by ordinal.
git-svn-id: trunk@22086 -
- PE_FILE_RELOCS_STRIPPED flag is meaningless for object files.
- Don't write PE_FILE_BYTES_REVERSED_LO as well, it is deprecated and GNU tools don't write it either.
- Don't set PE_FILE_32_BIT_MACHINE flag in x86_64 object files.
git-svn-id: trunk@21710 -
* Also simplified COFF symbol loading, separate array of symbol sizes is not needed because these sizes never change during the load.
git-svn-id: trunk@21704 -
* Enable smart linking on go32v2
* Adapted external linker script for long section names (ld 2.17 from fpcbuild repository does not seem to actually remove unused sections though)
* Do not pass '-lc' twice to external linker
* Pass -Map with correct filename to external linker if -Xm is specified on command line
* Debug sections for DJCOFF must have zero memory position and flag COFF_STYP_INFO (not COFF_STYP_NOLOAD).
git-svn-id: trunk@21435 -
* Fixed header data positions for DJCOFF executables, they need adjustment by stub size.
* Fixed symbol values in DJCOFF executables, they must be absolute.
* Fixed missing oso_common flag on TExeOutput.commonObjSection, causing incorrect COFF relocations to this section.
