* x86: Fix constraints for decode_significance*_x86Martin Storsjö2011-12-27
| | | | | | | | | | | | | | | | | | | Originally, prior to 8742a4ff8, the caller code was compiled within this condition: ARCH_X86 && HAVE_7REGS && HAVE_EBX_AVAILABLE && !defined(BROKEN_RELOCATIONS) Since HAVE_7REGS is defined as (ARCH_X86_64 || (HAVE_EBX_AVAILABLE && HAVE_EBP_AVAILABLE)) the subcondition HAVE_7REGS && HAVE_EBX_AVAILABLE is equal to HAVE_7REGS (for 32 bit at least). The correct simplification of the original condition thus is HAVE_7REGS, not HAVE_EBX_AVAILABLE. This fixes compilation in some cases where HAVE_EBP_AVAILABLE = 0 and HAVE_EBX_AVAILABLE = 1.

* x86: Tighten register constraints for decode_significance*_x86.Diego Biurrun2011-12-21
| | | | | | | On 32-bit OS X with gcc 4.0/4.2 and shared libraries enabled, the ebx register is not available, but required to assemble the functions. This reverts commit 8742a4f to a simplified version of the original constraints.

* x86: Require 7 registers for the cabac asmMartin Storsjö2011-12-12
| | | | | | | The change in 599b4c6ef didn't turn out to work properly on i386 on OS X, where it broke building with PIC enabled. Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: cabac: replace explicit memory references with "m" operandsMans Rullgard2011-12-11
| | | | | | | | This replaces the explicit offset(reg) memory references with "m" operands for the same locations. As a result, one fewer register operand is needed for these inline asm statements. Signed-off-by: Mans Rullgard <mans@mansr.com>

* x86: cabac: don't load/store context values in asmMans Rullgard2011-07-28
| | | | | | | | | | | Inspection of compiled code shows gcc handles these fine on its own. Benchmarking also shows no measurable speed difference. Removing the remaining cases in get_cabac_bypass_sign_x86() does cause more substantial changes to the compiled code with uncertain impact. Signed-off-by: Mans Rullgard <mans@mansr.com>

* x86: fix build with gcc 4.7Mans Rullgard2011-07-26
| | | | | | | | | | | | | | The upcoming gcc 4.7 has more advanced constant propagation resulting some inline asm operands becoming constants and thus emitted as literals, sometimes in contexts where this results in invalid instructions. This patch changes the constraints of the relevant operands to "rm" thus forcing a valid type. While obviously suboptimal, this is what older gcc versions already did, and there is no change to the code generated with these. Signed-off-by: Mans Rullgard <mans@mansr.com>
