Feature detection tasks moved from https://bugs.kde.org/show_bug.cgi?id=414270 (v8.1) and made part of v8.2 work. https://bugs.kde.org/show_bug.cgi?id=414268 https://bugs.kde.org/show_bug.cgi?id=413547 Addition of v8.2 faddp instructions: https://bugs.kde.org/show_bug.cgi?id=431556 Addition of FABS, FNEG and FSQRT instructions: https://bugs.kde.org/show_bug.cgi?id=432161 Addittion of v8.2 scalar FABD, FACGE, FACGT and FADD instructions: https://bugs.kde.org/show_bug.cgi?id=436411 Addition of vector FABD, FACGE, FACGT and FADD instructions: https://bugs.kde.org/show_bug.cgi?id=436873 Addition of arm64 v8.2 FCCMP, FCCMPE and FCMEQ instructions: https://bugs.kde.org/show_bug.cgi?id=438038 Adding compare-with-zero variants of arm64 v8.2 FCCMP, FCCMPE, FCMEQ, FCMGE and FCMGT instructions: https://bugs.kde.org/show_bug.cgi?id=438630 |
Created attachment 132577 [details] v8.2 instruction list (excluding variants) SUMMARY This container is for a collection of bugs to add Arm v8.2 instruction support. STEPS TO REPRODUCE Compile subject source with -march=armv8.2-a. If the compiler generates any of the instructions in the attached list (v8.2_excl_variants.txt), valgrind will exit with unknown instruction error. ADDITIONAL INFORMATION There are 71 v8.2 instructions, see attached list v8.2_excl_variants.txt. Most of these have scalar, vector, paired, fixed and floating point variants which brings the total number of instructions which need to be implemented to 123, see attached list v8.2_incl_variants.txt.
