* 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.
git-svn-id: trunk@21408 -
* Assign section indexes independent from symbol indexing.
* Fixed section flags not assigned while reading DJGPP object files.
* Fixed objData type for TDJCoffexeoutput.
* Fixed entry point address of DJGPP executables.
* Fixed filling exe section headers for DJGPP.
git-svn-id: trunk@21396 -
- removed empty destructor and checks for nil before .Free (they are done in tobject.free itself)
+ added COMDAT definitions.
git-svn-id: trunk@21383 -
that deal with paths/filenames with TPathStr (= ansistring) to prevent
cutting off long paths (no change in speed when compiling the compiler,
1% extra memory usage)
git-svn-id: trunk@21120 -
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 $)
git-svn-id: trunk@20801 -
* eliminate warnings in compiler (i386 & i368->x86_64) and minor refactorings
- comment out unused vars and types
- comment out unneeded comparisons (Longword <=> 0)
- suppress some "comparison always true|false" warnings
- tweak visiblity sections
git-svn-id: trunk@19385 -
* Changed alignment of .pdata section to 4.
+ Support saving RELOC_NONE relocations to .o files and reading them back on x86_64.
git-svn-id: trunk@19070 -
* Clear bits in section flags, that are only valid for object files
* Round section datasize up to filealignment (PECOFF v8 documentation requires this)
* Zero datapos and datasize for all sections w/o data, not just for .bss
* Produce IMPORT_ADDRESS_TABLE directory in exe header
* Entirely smartlink away unused DLLs (these used to have two terminating thunks left)
git-svn-id: trunk@17949 -
+ parsing of section directive for variables
+ section test
+ write section names in the assembler/binary writers correctly
* allow section only after ; and for embedded targets

{ Direct 32 bit sign extended,
win64 mingw GNU compiler
also generates this type
inside coff objects
We assume they are equivalent to
IMAGE_REL_AMD64_ADDR32 PM 2010-11-27 }
git-svn-id: trunk@16454 -
* assemble.pas (TInternalAssembler.WriteStab): Use RELOC_ABSOLUTE32 for
32-bit stab entry.
* ogcoff.pas: Add check for correct generated reloc section size.
* systems/t_win.pas: Use 0x400000 image base for x86_64 programs using
stabs debug information format.
git-svn-id: trunk@16056 -
* 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 -
* Warning when 64-bit object file contains 32-bit absolute relocations. In such case an executable image can be loaded into lower 4Gb of address space only.
git-svn-id: trunk@13110 -
* Proper handling of 64-bit COFF relocations.
* Use jumps with 32-bit relative addressing in imports on win64.
* This fixes are related to bug #13657. The bug is not fully fixed yet...
git-svn-id: trunk@13104 -
* Write zero to relocs in debug sections, which point to unused sections, eliminated by linker.
* It seems internal linker creates correct dwarf debug info now.
git-svn-id: trunk@13093 -
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 -
* Suppressed 2 unreachable code warnings.
* Now x86 compiler compiles without warnings and notes! It will be great to keep such state in future...
