53c943c5a1 + ELF linker: support writing DT_PREINIT_ARRAY/DT_INIT_ARRAY/DT_FINI_ARRAY dynamic tags. Still misses a lot of sanity checks, and does not sort entries.

a4053370fc * ELF linker: track relocation style (REL or RELA) of each input section and use it instead of global default on MIPS targets. This fixes internal linking of tests/test/units/system/tres*.pp.

7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
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).

3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc 
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.

1f8a67f552 + Property TObjSymbol.ObjData, allows to access owning TObjData for external/common symbols, i.e. ones with ObjSection=nil. 
* For common symbols, report objdata of the original ObjSymbol, not of the resolving one, so the map file shows where it comes from.
+ TElfExeOutput.OrderOrphanSections method, handles object sections not mentioned in script similar to ld.
- t_linux.pas: removed sections that are not part of ld scripts, they are now handled by OrderOrphanSections.

Revision: 23488
Author: yury
Date: 22 Jan 2013 15:47:52
Message:
* Implemented { %DELFILES file1 file2 ... } directive for tests. Primarily it is needed to delete shared libraries used by tests when TEST_DELTEMP=1. When testing on a real Android device, it is not good to run tests on flash memory partitions. Android devices have 1Mb RAM based tempfs partition for /tmp folder, which is ideal for running tests. Since 1Mb is very small size these days, it is needed to clean all test leftovers. Test shared libraries are the biggest leftovers and this new DELFILES directive will help to delete them.
* During remote execution, use && as a command separator after important commands such as CD to ensure that the command succeeded before running other commands. Group other commands using curly braces { }.

* I've found that libc on Android does not implement widechar case functions such as towupper(). Such functions are just wrappers over regular char functions. Therefore the whole cwstring unit is useless for Android. For now I've added stub cwstring unit for Android and reverted all Android specific changes in unix/cwstring.pp. Later, Unicode manager for Androud should be implemented using libicuuc, which is default Android lib.

* Android does not have libiconv, so don't use it in cwstring unit. For now support only UTF-8 code page in ansistrings. Later it is possible to use libicuuc for code page conversions on Android.

* Rework of Android startup code. It is needed to always link to libc on android to implement finalization and environment variables in shared libraries.
* Cleanup of Android linker.
* Use only INSERT command in the linker script to inject custom .fpc sections. Whole linker script duplication is nor needed anymore.
* Use BFD linker, since GOLD linker does not support INSERT command. Other incompatibilities may also exist.
* Enable tf_smartlink_sections for i386-android.

a7e7d97da6 * ELF linker: fixed written values of STT_TLS symbols, they must be relative to PT_TLS segment address. 
* Made name of dynamic interpreter variable, it is now set correctly for each target.
- Removed setting header flags for ARM. This functionality belongs to CPU-specific unit anyway, and probably must be implemented using object attributes in modern ABIs.

0369a30f49 * Internal linker: made sec_rodata_norel read-only. 
* For Win32 and Win64 targets made sec_rodata read-only, too (for these targets it doesn't matter if read-only section contains relocations).

2c011312db * Changed TElf32Header and TElf64Header definitions, making them look closer to canonical ones (first 16 bytes are a single array field, addressable via EI_xx indices).

1aea22a6ca + Internal linker: generic and ELF-specific support for grouped sections, allow same symbol to be defined in several COMDAT groups. 
* ELF linker: don't make unresolved weak symbols dynamic if linking statically (-Xt in command line).
* Now internal linker produces working executable for tw14265 also on i386-linux when compiling manually (still unable to locate required libraries when run from test suite).

277200e7ae + ELF linker: Support writing RELATIVE dynamic relocations ahead of the rest, and their number in DT_REL[A]COUNT dynamic tag (still needs changes in CPU-specific code to function properly). 
* TElfObjInput.LoadSymbols: ignore STT_SECTION symbols for sections that were ignored in LoadSections().
* TElfObjInput: changed symtabndx (index of .symtab/.dynsym section) into field and its type to unsigned.

d019670495 - Removed generic implementation of TObjData.sectionname, its existence is useless because it is completely overridden by all TObjData descendants. 
- Removed separate ELF section names for PIC. The only difference was .data named .data.rel; however .rel suffix has nothing to do with PIC. It only signifies that the section has relocations so such sections can be grouped together in output file and reduce number of pages for dynamic linker to visit  while resolving the relocations at load time. At the same time, no existing link scripts distinguish between .rel and any other suffix (except .rel.ro, but it's a different story), meaning that long section names will break .rel grouping.
While support for .data.rel can be added similar to existing rodata handling (separate sec_data and sec_data_norel sections), this doesn't seem worth the trouble.

4410fe86d2 * ELF linker: moved some code (which must be executed only once when linking with separate debug file) from MemPos_Start into AfterUnusedSectionRemoval, this removes some checks and simplifies things. 
* Simplified .shstrtab handling between passes by using oso_debug_copy attribute on it.
- Don't recreate segment mapping: only debug sections are removed between passes, and they are never part of any segment.

6023f73e2a * ELF linker: improved dynamic symbol handling. 
+ Read .gnu.version sections and ignore local symbols and symbols with non-current version.
  + Check that external symbols are actually present in dynamic objects.

6d70009f06 + ELF linker. Works on x86_64-linux and i386-linux good enough to pass the testsuite, but still requires a lot of work in nearly all aspects. In particular, no attempt to resolve symbols from shared libs is done, everything is just treated as imports. Symbol versioning isn't supported either. 
x86_64 is the most elaborated, has some degree of indirect function (GNU_IFUNC) and TLS support, so it is even able to link with static libc/pthreads code (tw14265) and produce an executable that can launch (but still fails due to invalid DWARF unwind info).

i386 produces working shared libraries if they are compiled with -Cg, without one your mileage may vary. tw14265 does not link yet due to missing COMDAT group support.

339d06aa58 * When writing section names of .o files, let sh_name of sections with relocations point into names of corresponding relocation sections past the .rel/.rela prefix. In case of smartlinked sections this saves almost half of .shstrtab section size. 
* Fixed writing of weak defined symbols, TLS and GNU_IFUNC symbols.

c41b407119 * Changed TObjSection.WriteStr method to write a zero byte after the string. 
+ 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.
