* x86-64 bug fix: Fix stab generation for x86-64.Shinichiro Hamaji2009-04-181-3/+3
| | | | The size of a stab entry is 12 bytes even in 64bit environments. We must use int instead of long to keep the size of stab entries.
* Better DLL support on x86-64.Shinichiro Hamaji2009-04-181-8/+39
| | | | | | | | | | | | - Add a macro TCC_OUTPUT_DLL_WITH_PLT. -- Now, the DLL with PLT support works only on x86-64, but we may be able to support it on all architectures eventually. - Define TCC_OUTPUT_DLL_WITH_PLT when target architecture is x86-64. - Current status (x86-64): -- Main program should be able to call functions in shared objects. -- Main program should be able to use global variables in shared objects. -- Shared objects should be able to call functions in main program. -- Shared objects can NOT use global variables in main program. - To fix the last issue, we may need to add support of -fPIC option in our code generator.
* First naive DLL support on x86-64.Shinichiro Hamaji2009-04-181-3/+33
| | | | This logic depends on x86_64-gen.c and doesn't work with objects compiled by GCC.
* Add support of x86-64.Shinichiro Hamaji2008-12-021-3/+136
| | | | | | | | | | | | | | | | | | | | | | Most change was done in #ifdef TCC_TARGET_X86_64. So, nothing should be broken by this change. Summary of current status of x86-64 support: - produces x86-64 object files and executables. - the x86-64 code generator is based on x86's. -- for long long integers, we use 64bit registers instead of tcc's generic implementation. -- for float or double, we use SSE. SSE registers are not utilized well (we only use xmm0 and xmm1). -- for long double, we use x87 FPU. - passes make test. - passes ./libtcc_test. - can compile tcc.c. The compiled tcc can compile tcc.c, too. (there should be some bugs since the binary size of tcc2 and tcc3 is differ where tcc tcc.c -o tcc2 and tcc2 tcc.c -o tcc3) - can compile links browser. It seems working. - not tested well. I tested this work only on my linux box with few programs. - calling convention of long-double-integer or struct is not exactly the same as GCC's x86-64 ABI. - implementation of tcc -run is naive (tcc -run tcctest.c works, but tcc -run tcc.c doesn't work). Relocating 64bit addresses seems to be not as simple as 32bit environments. - shared object support isn't unimplemented - no bounds checker support - some builtin functions such as __divdi3 aren't supported

* Make tccelf.c 64bit ready.Shinichiro Hamaji2008-12-021-9/+20
| | | | | | | - Use REL_SECTION_FMT instead of ".rel%s". - Use PTR_SIZE instead of sizeof(int) for GOT entries. - Use sizeof(ElfW(Dyn)) instead of magic number 8. - Use TCC_ELFCLASS instead of ELFCLASS32.
* Introduce ElfW macro and ELFW to encapsulate the difference between Elf32_* ↵Shinichiro Hamaji2008-12-021-163/+173
| | | | and Elf64_*. Also, introduce ElfW_Rel and SHT_RELX for difference between REL and RELA.
* Allow to use libgcc instead of libtcc1Daniel Glöckner2008-09-121-0/+6
| | | | | | | | | | | | | | | This patch adds a switch --with-libgcc to configure. When passed it prevents libtcc1.a from being built and links to /lib/libgcc_s.so.1 instead of PREFIX/lib/tcc/libtcc1.a. It will work on ARM when using libgcc from GCC >= 4.2.0. Prior versions don't have the __floatun[sd]i[sdx]f functions. It won't work on i386 because of two missing symbols emitted when floats are cast to integers, but users can provide those symbols (global short constants) in their code if needed. Daniel
