[Bug target/115789] gcc miscompile itself with CFLAGS -O3 -march=rv64gcv_zvl256b

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115789 --- Comment #5 from Craig Topper --- Isn’t -mstrict-align the default? It is in LLVM.

[Bug target/113095] RISC-V: movcc no longer used for coremark crc functions with -mtune=sifive-7-series

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113095 --- Comment #3 from Craig Topper --- Our FPGA data is showing this as a 5% regression. I'll try to check on an Unmatched board to confirm.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113095 --- Comment #2 from Craig Topper --- The branch+mv macrofusion should execute together. The visible latency to other instructions is 1 cycle. The hardware can predicate most ALU instructions, not just mv. So even better would be putting the xor

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110201 --- Comment #3 from Craig Topper --- I don't have a testsuite. I saw that gcc had crypto builtins and I happened to noticed the tests in gcc weren't passing constant arguments. We also have a divergence in names between clang and gcc for some c
