Hi all,
This is a patch which will fix PR63424.
It implements signed/unsigned max/min pattern for V2DI mode in terms
of vcondv2div2di pattern.
In this particular case, VEC_COND_EXPR (V2DImode) is generated as
aarch64 target supports it (vcond<mode><mode> for VALL). The
VEC_COND_EXPR will further folded into MIN_EXPR/MAX_EXPR in dom pass
unconditionally. Later in expand pass, the compiler tries to expand
min_expr using standard RTL operation. It fails, because aarch64
target don't have minv2di3 pattern implemented. It then tries to
generate conditional move and compare&branch sequence, all fails. At
last it falls into libfunc call, no luck either. An ICE to complain
about this.
aarch64-none-elf toolchain has been tested on the model, no regressions.
Is it Okay for trunk?
