Hi Jeff,
I'm really sorry for the regression failure.
I missed one patch to fix these issues.
Thanks for your review.
The GTY skip makes GGC clean the registered functions wrongly in lto.
Example:
riscv64-unknown-elf-gcc -flto gcc/testsuite/gcc.target/riscv/rvv/base/bug-10.c
-O2 -march=rv64gcv
In file included from bug-10.c:2: internal compiler error: Segmentation fault
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins.cc (registered_function):
Remove skip at decl.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/base/bug-10.c: New test.
My point is removing the "skip" is clearly wrong as it causes all kinds
of regressions.
This can't be integrated as-is.
