Re: [fpc-devel] implementation AVX for Intel/AMD Prozessors
Op Sun, 18 Sep 2011, schreef Torsten: I do not know exactly which functions need to be changed. I'm hoping for tips. You will have to be a bit exploring here; AVX is a major upgrade to the x86 instruction set, and there will likely not be a few routines that need to be changed. First step is to make sure they can be used in assembler routines. The assembler is largely table driven, so it you have added them to the tables, a lot should work already. Nevertheless, I expect that modifications are necessary in the both the assembler generators (ag*.pas) and assembler readers (ra*.pas) due to the additional operand that needs to be written/parsed. Only when the point is reached that the instructions are handled well by the assembler reader/writers you could start by adding code generator support.

[fpc-devel] implementation AVX for Intel/AMD Prozessors
Hi, im starting with implementation of AVX (Intel/AMD) in fpc-assemblercode. I use in first step a external assembler (linux as). In this case, it is easy to use XMM-Register (max. 3 parameter) (only change the file x86ins.dat, examble: [VMOVDQA] (Ch All, Ch None, Ch None) xmmreg, xmmrm \361\... For use of YMM-Register i have change the file x86reg.dat NR_YMM0,$0700,ymm0,%ymm0,ymm0,ymm0,21,21,17,OT_YMMREG,0 NR_YMM1,$0701,ymm1,%ymm1,ymm1,ymm1,22,22,18,OT_YMMREG,1 NR_YMM2,$0702,ymm2,%ymm2,ymm2,ymm2,23,23,19,OT_YMMREG,2 NR_YMM3,$0703,ymm3,%ymm3,ymm3,ymm3,24,24,20,OT_YMMREG,3 NR_YMM4,$0704,ymm4,%ymm4,ymm4,ymm4,25,25,21,OT_YMMREG,4 NR_YMM5,$0705,ymm5,%ymm5,ymm5,ymm5,26,26,22,OT_YMMREG,5 NR_YMM6,$0706,ymm6,%ymm6,ymm6,ymm6,27,27,23,OT_YMMREG,6 NR_YMM7,$0707,ymm7,%ymm7,ymm7,ymm7,28,28,24,OT_YMMREG,7 NR_YMM8,$0708,ymm8,%ymm8,ymm8,ymm8,-1,-1,25,OT_YMMREG,0,64 NR_YMM9,$0709,ymm9,%ymm9,ymm9,ymm9,-1,-1,26,OT_YMMREG,1,64 NR_YMM10,$070a,ymm10,%ymm10,ymm10,ymm10,-1,-1,27,OT_YMMREG,2,64 NR_YMM11,$070b,ymm11,%ymm11,ymm11,ymm11,-1,-1,28,OT_YMMREG,3,64 NR_YMM12,$070c,ymm12,%ymm12,ymm12,ymm12,-1,-1,29,OT_YMMREG,4,64 NR_YMM13,$070d,ymm13,%ymm13,ymm13,ymm13,-1,-1,30,OT_YMMREG,5,64 NR_YMM14,$070e,ymm14,%ymm14,ymm14,ymm14,-1,-1,31,OT_YMMREG,6,64 NR_YMM15,$070f,ymm15,%ymm15,ymm15,ymm15,-1,-1,32,OT_YMMREG,7,64 Next step is change the files cpubase, cgbase, aasmcpu, What do i consider?

Op Sun, 18 Sep 2011, schreef Florian Klämpfl: I'am not sure if the ymm registers should be an own register class. After all, they are a superset of xmm Exactly. Since if xmm0 is allocated, ymm0 is allocated too; the register allocator should treat them as a single register. xmm0 and ymm0 are a subregister of the same superregister.
