* arm64: Implement __clear_cache.Edmund Grimley Evans2015-03-085-1/+63
| | | | | | __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

* arm64: Optimise some integer operations with a constant operand.Edmund Grimley Evans2015-03-073-2/+243

* tccgen.c: Optimise 0<<x, 0>>x, -1>>x, x&0, x*0, x|-1, x%1.Edmund Grimley Evans2015-03-071-10/+25
| | | | | | | | | 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.

* Add __builtin_return_address.Edmund Grimley Evans2015-03-062-1/+14
| | | | | | 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.

| | | | | | | | | | | | | | | Author: Thomas Preud'homme <robotux@celest.fr> Date: Tue Dec 31 23:51:20 2013 +0800 Move logic for if (int value) to tccgen.c Move the logic to do a test of an integer value (ex if (0)) out of arch-specific code to tccgen.c to avoid code duplication. This also fixes test of long long value which was only testing the bottom half of such values on 32 bits architectures. I don't understand why if () in gtst(i) was removed. This patch allows to compile a linux kernel v.2.4.26 W/o this patch a tcc simply crashes.
