--- Comment #3 from Bruce Hoult <bruce at hoult dot org> ---
gah! It deleted the description, URL, keywords etc I was in the middle of
writing when I added an attachment of the compiler output! Sorry!
Code:
void *memset();
void a(void *b){ memset(b, 0, 1lu); }
Compile command:
riscv64-unknown-elf-gcc -O -c -march=rv64gc_xtheadvector bug.c
GCC version: 14.0.1 self compiled 306a4c322353 Mar 2 Daily bump.
System type: RISC-V.
Happens on LicheePi 4A, VisionFive 2, QEMU, and cross-compiler on Godbolt.
The original code was the main program for a program that used RVV intrinsics
in other files, but not in this one. For simplicity the same options were
passed for all source files.
Compiler build options (local .. I don't know what Godbolt uses):
/root/riscv-gnu-toolchain/gcc/configure --target=riscv64-unknown-elf
--prefix=/root/_install --disable-shared --disable-threads
