Edmund Grimley Evans f0b7566181 tccelf.c: Reset sym after call to build_got. 
The call to build_got can cause symtab_section->data to be reallocated
(build_got -> add_elf_sym -> put_elf_sym -> section_ptr_add ->
section_realloc -> tcc_realloc). This is not obvious on a cursory
inspection, but fortunately Valgrind spotted it immediately.
Are there other, similar bugs that Valgrind did not detect?

Edmund Grimley Evans 5de8b5638f .gitignore: Add lib/arm64. 2015-03-10 22:38:26 +00:00
Edmund Grimley Evans 0e79df499a tccgen.c: (!nocode_wanted) -> (nocode_wanted) in arm64 part. 2015-03-10 22:37:36 +00:00
Edmund Grimley Evans d73b488401 arm64: Implement __clear_cache. 
__clear_cache is defined in lib-arm64.c with a single call to
__arm64_clear_cache, which is the real built-in function and is
turned into inline assembler by gen_clear_cache in arm64-gen.c

Edmund Grimley Evans d854dede03 arm64: Optimise some integer operations with a constant operand. 2015-03-07 17:42:08 +00:00
Edmund Grimley Evans ac70e6b840 tccgen.c: Optimise 0<<x, 0>>x, -1>>x, x&0, x*0, x|-1, x%1. 
More precisely, treat (0 << x) and so on as constant expressions, but
not if const_wanted as we do not want to allow "case (x*0):", ...

Do not optimise (0 / x) and (0 % x) here as x might be zero, though
for an architecture that does not generate an exception for division
by zero the back end might choose to optimise those.

Edmund Grimley Evans 9163393476 arm64-gen.c: In load(), do not sign-extend 32-bit VT_CONST. 2015-03-07 17:32:39 +00:00
Edmund Grimley Evans 238e760a29 Add __builtin_return_address. 
Implementation is mostly shared with __builtin_frame_address.
It seems to work on arm64, i386 and x86_64. It may need to be
adapted for other targets.

Edmund Grimley Evans 40f7e11c53 tccgen.c: Make sure that gen_op always returns an rvalue. 
Either this fix, or an alternative one, is required for arm64.

tcc.h: Add greloca and put_elf_reloca.
tccelf.c: Add put_elf_reloca, a generalisation of put_elf_reloc.
tccgen.c: On x86_64, use greloca instead of greloc in init_putv.

Edmund Grimley Evans 86c850fc58 tcc-doc.texi: Explain VT_LLOCAL a bit better. 
And delete the sentence about it being removed.

Edmund Grimley Evans ff3f9aa6ba Fix handling of case_reg in switch statement. 
The back end functions gen_op(comparison) and gtst() might allocate
registers so case_reg should be left on the value stack while they
are called and set again afterwards.
