Shinichiro Hamaji 85d016b507 x86-64: Remove code for debug print. 
Now, we concat buffers before relocation. So this only happens when users try creating >2GB binary.

Shinichiro Hamaji 39a4b859d4 x86-64: Fix cast from integers to pointers. 
Now,

./tcc -run -DTCC_TARGET_X86_64 tcc.c -run tcctest.c

works!
 2009-04-18 15:08:02 +02:00
Shinichiro Hamaji 51a7f163ad Work around for the issue TCC doesn't handle -2147483648 properly. 
TCC produces code which is incompatible with GCC for the following code:

    printf("%lld\n", (long long)-2147483648);
    printf("%lld\n", (long long)-2147483649);

For now, just avoid using the corner value.
 2009-04-18 15:08:01 +02:00
Shinichiro Hamaji 83fd36333a Fixes for issues I've just found/introduced to x86 TCC. 
- Cast from pointer to long long makes TCC output an error. Use cast to int before we apply shift operation for a pointer value.
- Removed test cases for casts from pointer to char/short because they produce warning.

Shinichiro Hamaji de3f0a46fe Fix for x86-64: The first and second arguments of memcpy must be pointers. 2009-04-18 15:08:01 +02:00

Shinichiro Hamaji 9fe28b610e x86-64: Make ABI for long double compatible with GCC. 
- Now we use x87's stack top the long double return values.
- Add rc_fret and reg_fret, wrapper functions for RC_FRET and REG_FRET.
- Add a test case to check if strto* works OK.

Shinichiro Hamaji fcf2e5981f x86-64: Combine buffers of sections before we call tcc_run(). 
- Now we can run tcc -run tcc.c successfully, though there are some bugs.
- Remove jmp_table and got_table and use text_section for got and plt entries.
- Combine buffers in tcc_relocate().
- Use R_X86_64_64 instead of R_X86_64_32 for R_DATA_32 (now the name R_DATA_32 is inappropriate...).
 2009-04-18 15:08:01 +02:00
Shinichiro Hamaji 830b7533c9 Generate PIC code so that we can create shared objects properly. 
- Add got_table in TCCState. This approach is naive and the distance between executable code and GOT can be longer than 32bit.
- Handle R_X86_64_GOTPCREL properly. We use got_table for TCC_OUTPUT_MEMORY case for now.
- Fix load() and store() so that they access global variables via GOT.

- Handle R_X86_64_GOTPCREL.
- Output R_X86_64_RELATIVE reloc generated from R_X86_64_64.

Shinichiro Hamaji 754b0beb7d x86-64 bug fix: Fix stab generation for x86-64. 
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.
 2009-04-18 15:07:09 +02:00
Shinichiro Hamaji e6db5f5fb6 x86-64 bug fix: Use stack with alignment just like 32bit environments. 2009-04-18 15:07:09 +02:00
Shinichiro Hamaji 06fa15fb99 x86-64: Save RDX and RCX before we use them as function parameters. 
When the function call is indirect, these registers may be broken to load a function pointer.
 2009-04-18 15:07:09 +02:00
Shinichiro Hamaji ebb874e216 Remove multiple definition error caused by combination of x86-64 and va_list. 
We need malloc and free to implement va_start and va_end.
Since malloc and free may be replaced by #define, we add __builtin_malloc and __builtin_free.
 2009-04-18 15:07:09 +02:00
Shinichiro Hamaji 6512d9e2ea Add check for invalid numbers. 
If there are some characters after TCC parses a number, it is an error.

This bug was reported on list:

 2009-04-18 15:07:09 +02:00
Shinichiro Hamaji af6cbc48d1 Fix overrun in decl_initializer_alloc. 
This bug was reported on

http://lists.gnu.org/archive/html/tinycc-devel/2009-03/msg00035.html

This happens because parser of array initializer doesn't stop to read until semi-colon or comma.

Shinichiro Hamaji 040ef000e4 Better DLL support on x86-64. 
- 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.

Shinichiro Hamaji fe8f230ab6 First naive DLL support on x86-64. 
This logic depends on x86_64-gen.c and doesn't work with objects compiled by GCC.
