Hi, in the somewhat convoluted vector code of PR119114 we extracting a <signed-boolean:1> mask value from a vector mask. After some middle-end simplifications we end up with a value of -2. Its lowest bit is correctly unset representing "false". When initializing a bitmak vector from values we compare the full value/register against zero instead of just the last bit. This causes erroneous mask values. This patch masks the values by & 0x1 before comparing against 0. Regtested on rv64gcv_zvl512b, let's see what the CI has to say. Regards Robin PR target/119114 gcc/ChangeLog: * config/riscv/autovec.md: Apply & 0x1 mask when initializing bitmask vector. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/pr119114.c: New test.
OK jeff
