* test/avx: remove deleted instructionsH. Peter Anvin2010-08-161-7/+0
| | | | | | Remove the deleted VPERMIL2 instructions. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* insns.dat: permit contracted forms for VBLENDVPH. Peter Anvin2010-08-161-4/+4
| | | | | | | Allow implicit operands for VBLENDVP, just as for other instructions, since the semi-legacy forms now are removed. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* assmemble.c: fix VEX.W logicH. Peter Anvin2010-08-161-2/+2
| | | | | | | Fix the generation logic for VEX.W, which unfortunately got the wrong constants. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* insns.dat: SSE encoding of VBLEND with VEX prefix is forbiddenH. Peter Anvin2010-08-161-4/+0
| | | | | | | | Version 7 of the AVX spec specifically forbids (#UD) using the 66 0F 38 14/15 forms of the BLENDV instructions with a VEX prefix; those encodings are strictly legacy SSE 4.1. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* insns.dat: updates from AVX v7H. Peter Anvin2010-08-161-184/+235
| | | | | | | | | | Updates from the AVX version 7 specification: mostly tightening of the rules for VEX.L and VEX.W, but remove the VPERMIL2 instructions. Also encode all the full-length forms of the VCMP instructions and prefer those for the disassembly. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* assemble: handle vex.ligH. Peter Anvin2010-08-163-11/+19
| | | | | | | AVX version 7 introduces the concept of .lig, meaning VEX.L is ignored. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* vex: change .wx to .wig to match the latest AVX specH. Peter Anvin2010-08-162-5/+5
| | | | | | | | Change the .wx (ignore the W field) to .wig, to match the latest version of the AVX specification. This is not a functional change, but just makes instruction patterns a little easier to write. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* doc: Update -O option descriptionCyrill Gorcunov2010-08-161-4/+0
| | | | | | | | We use -Ox by default since Nasm-2.09 so "-O0" is not longer "default" option. But first paragraph still has the reference which confuses people. Get rid of it. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>

* preproc.c: Context-through single macros expansion is deprecatedCyrill Gorcunov2010-08-111-10/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For now we inform users about their sources need to be updated and also since _all_ context case are legit for single macros only we split lookup into two phases: 1) Lookup in active context, which is perfectly valid 2) Lookup in external contexts, which will be deprecated soon. If (2) happens we yield warning. A typical testcase is --- %macro one 0 %push %$a: %assign %$b 12 %push mov eax, %$a mov eax, %$b ; hit -- context through %pop %pop %endmacro one --- Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>

* BR3041451: Implement upper bound for %rep counterCyrill Gorcunov2010-08-093-1/+15
| | | | | | | | | | Since %rep counter is a 64 bit signed integer we have to use some "maximum possible value" limit (upper bound) otherwise there may be a situation when %rep counter is 0 or even negative while user has been passing big positive integer value.

* Improve process_ea and introduce -OLVictor van den Elzen2010-07-247-72/+144
| | | | | | | | | | | | | | | | | | | Two fixes: 1. Optimization of [bx+0xFFFF] etc 0xFFFF is an sbyte under 16-bit semantics, so make sure to check it right. 2. Don't optimize displacements in -O0 Displacements that fit into an sbyte or can be removed should *not* be optimized in -O0. Implicit zero displacements are still optimized, e.g.: [eax] -> 0 bit displacement, [ebp] -> 8 bit displacement. However explicit displacements are not optimized: [eax+0] -> 32 bit displacement, [ebp+0] -> 32 bit displacement. Because #2 breaks compatibility with 0.98, I introduced a new optimization level: -OL, legacy.
