[PATCH] [testsuite] [riscv] uninit-pred-9_b bogus warning

[Alexandre Oliva]

Like other platforms, riscv hits the uninitialized warning because the
optimizations don't eliminate the nonviable path that would enable it
to be omitted.

Regstraped on x86_64-linux-gnu, also tested with crosses to riscv64-elf
and arm-eabi.  Ok to install?


for  gcc/testsuite/ChangeLog

	* gcc.dg/uninit-pred-9_b.c: Add riscv*-*-* to the xfail list
	for the bogus warning.

Disinformation flourishes because many people care deeply about injustice
but very few check the facts.  Ask me about <https://stallmansupport.org>
