* Add support for struct > 4B returned via registersThomas Preud'homme2013-11-221-4/+5
| | | | | | | | On ARM with hardfloat calling convention, structure containing 4 fields or less of the same float type are returned via float registers. This means that a structure can be returned in up to 4 double registers in a structure is composed of 4 doubles. This commit adds support for return of structures in several registers.
* i386-gen: preserve fp control word in gen_cvt_ftoigrischka2013-08-281-63/+28
| | | | | | | | | | | | | | | | | | | | | | | - Use runtime function for conversion - Also initialize fp with tcc -run on windows This fixes a bug where double x = 1.0; double y = 1.0000000000000001; double z = x < y ? 0 : sqrt (x*x - y*y); caused a bad sqrt because rounding precision for the x < y comparison was different to the one used within the sqrt function. This also fixes a bug where printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2)); would print 100, 99 Unrelated: win32: document relative include & lib lookup win32: normalize_slashes: do not mirror silly gcc behavior This reverts part of commit 8a81f9e1036637e21a47e14fb56bf64133546890 winapi: add missing WINAPI decl. for some functions
* Add support for load/store of _Bool valueThomas Preud'homme2013-06-141-1/+1
| | | | | Add support for loading _Bool value in i386, x86_64 and arm as well as support for storing _Bool value on arm.

* Improved variable length array support.James Lyon2013-04-271-0/+39
| | | | | | | | | | | | | | | VLA storage is now freed when it goes out of scope. This makes it possible to use a VLA inside a loop without consuming an unlimited amount of memory. Combining VLAs with alloca() should work as in GCC - when a VLA is freed, memory allocated by alloca() after the VLA was created is also freed. There are some exceptions to this rule when using goto: if a VLA is in scope at the goto, jumping to a label will reset the stack pointer to where it was immediately after the last VLA was created prior to the label, or to what it was before the first VLA was created if the label is outside the scope of any VLA. This means that in some cases combining alloca() and VLAs will free alloca() memory where GCC would not.
* Fixed i386 calling convention issue and CMake build on i386.James Lyon2013-04-261-0/+8
| | | | | The i386 calling convention expects the callee to pop 1 word of the stack when performing a struct ret.
* Tests in abitest.c now work on Win32.James Lyon2013-04-181-8/+27
| | | | | | | I expect that Linux-x86 is probably fine. All other architectures except ARM are definitely broken since I haven't yet implemented gfunc_sret for these, although replicating the current behaviour should be straightforward.

* i386: We can change 'lea 0(%ebp),r' to 'mov %ebp,r'Kirill Smelkov2012-11-161-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because that mov is 1 byte shorter, look: int *func() { return __builtin_frame_address(0); } before patch: 00000000 <func>: 0: 55 push %ebp 1: 89 e5 mov %esp,%ebp 3: 81 ec 00 00 00 00 sub $0x0,%esp 9: 8d 45 00 lea 0x0(%ebp),%eax // <- here c: e9 00 00 00 00 jmp 11 <func+0x11> 11: c9 leave 12: c3 ret after patch: 00000000 <func>: 0: 55 push %ebp 1: 89 e5 mov %esp,%ebp 3: 81 ec 00 00 00 00 sub $0x0,%esp 9: 89 e8 mov %ebp,%eax // <- here b: e9 00 00 00 00 jmp 10 <func+0x10> 10: c9 leave 11: c3 ret

| | | | These loads clobbered ebx as TinyCC wanted to load the address into st0.
