* Remove unused variablesThomas Preud'homme2011-05-161-3/+6
| | | | | Remove unused local variables and declare them conditionally when they are used only on some architectures.

| | | | R_X86_64_PLT32 for .so doesn't need DLL relocation.
* Handle r_addend and R_X86_64_PLT32 properly.Shinichiro Hamaji2010-12-281-7/+6
| | | | | | | | | - r_addend should be applied for PLT entries as well - R_X86_64_PLT32 should be handled just like R_X86_64_PC32 - spec says GLOB_DAT and JUMP_SLOT don't need r_addend (not tested) http://www.x86-64.org/documentation/abi.pdf Now we can -run ELF objects generated by GCC.

| | | | This is needed to reach tinycc's PLT from the compiled program.
* Don't load libtcc1 on arch where it doesn't existThomas Preud'homme2010-05-011-3/+7
| | | | | | | ARM architecture doesn't have any libtcc1 implementation but tcc load libtcc1.a in all case. This patch add a conditional preprocessor instruction to load libtcc1.a only when there is an implementation for the target architecture.
* Link alias symbols togetherThomas Preud'homme2010-05-011-0/+20
| | | | | | | | Make sure alias symbols resolve to the same address in program .bss or .data section. This ensure for example that if a program reference environ (via an extern char **environ declaration) and the libc change its value via the __environ alias after the R_ARCH_COPY relocation have been performed, then the program will see the new value.

* Clean changes introduced by 47abdbdThomas Preud'homme2010-04-201-66/+86
| | | | | | | | | | | | * Replace the save/load_buffer_state by a dynarray approach: - Filename and libname are added to a dynarray when first encountered - Load repeatedly the files in the dynarray until no new undefined symbol are encountered * Replace snprintf by sprintf in libname_to_filename * Use tcc_fileextension in filename_to_libname * Introduce a tcc_strcpy_part fonction to copy only a subset of a string * Move new_undef_syms declaration from tcc.h to tccelf.c

* Recognize -Wl,-BsymbolicDetlef Riekenberg2010-01-261-0/+4
| | | | | | | | | | | | | | | Without -Bsymbolic, a symbol/function in a *.so can be overridden by a symbol/function in the main module. That is the default search order, but not supported by tcc. With -Bsymbolic, the linker tries to resolve a symbol/function in the current module first. The loader in tcc implements this search order. We do not distinguish -Bsymbolic and -Bsymbolic-function -- By by ... Detlef

The two patches attached address a few problems (trying to explain to the best of my knowledge; i am not very familiar with ELF and the FreeBSD ELF conventions): 1. ELF file format tcc produces an ELF executable which is good for linux but not for FreeBSD. It misses the PHDR section which is almost mandatory for shared executables, puts in the .dynsym section some relocation info that FreeBSD expects to be in .got, and expect the relocation sections to be contiguous. patch-tccelf.c tries to address the above problem using conditional sections (so hopefully can be imported upstream) and also adds the ability to override the name of the dynamic loader through an environment variable (this is important to debug tcc). 2. predefined macros patch-libtcc.c adds/fixes some predefined macros when compiling on FreeBSD: these are __FreeBSD__ and the usual set of __i386__ and __unix__ variants. It also sets __INTEL_COMPILER so we can grab the __aligned macro from cdefs.h , otherwise many programs would fail The resulting elf file is still not 100% correct -- if you strip it, the program will not run (presumably there is some dangling reference). Other than that, program do seem to run correctly. It would be nice to integrate these patches in the main repository. The FreeBSD specific code is in #ifdef so it should not harm linux users cheers luigi
