After running my tests on an updated tree, here is what I have noted: - I need to adjust vadd's target in scan-assembler directives: arm*-*-* instead of arm*-*-* otherwise the tests are not executed for targets such as arm-none-eabi. - vzip/vuzp tests now PASS after Alan's fix. I have run the following targets: arm-none-linux-gnueabihf arm-none-linux-gnueabi arm-none-eabi armeb-none-linux-gnueabihf armeb-none-linux-gnueabi aarch64-none-elf aarch64_be-none-elf aarch64-none-linux-gnu All the arm* configs have the same 1164 PASS / 18 FAIL - vadd's scan-assembler for vadd.i64 (as already discussed) - vclz tests currently fail at optimization levels starting with -O1 - vqadd test fails when compiled with -Os For aarch64, aarch64-none-elf and aarch64-none-linux-gnu have hopefully the same results (1152 PASS, 30 FAIL, 2 UNRESOLVED): - vadd's scan-assembler FAIL when optimizing: vadd of vectors of 1 64-bits element, and use of fadd for vectors of FP values. These tests pass at -O0 - vqadd and vqsub -Og -g: ICE In addtion, for aarch64_be (1108 PASS, 74 FAIL, 6 UNRESOLVED): - vldX, vldX_lane, vzip and vuzp: ICE at any optim level (incl -O0) Christophe.
