Subject: [RS6000] Power10 vec-splati-runnable multiple test failures
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5c1506304c52c29497a12c65734caaaa99996f77;p=gcc.git

[RS6000] Power10 vec-splati-runnable multiple test failures

FAIL: gcc.target/powerpc/vec-splati-runnable.c 1 blank line(s) in output
FAIL: gcc.target/powerpc/vec-splati-runnable.c (test for excess errors)
Excess errors:
rs6000_emit_xxspltidp_v2df called ...

and running the test fails.  As the comment says
  /* Although the instruction says the results are not defined, it does seem
     to work, at least on Mambo.  But no guarentees!  */
So the simulator works but not real hardware.

gcc/
	* config/rs6000/rs6000.c (rs6000_emit_xxspltidp_v2df): Delete
	debug printf.  Remove trailing ".\n" from inform message.
	Break long line.
gcc/testsuite/
	* gcc.target/powerpc/vec-splati-runnable.c: Don't abort on
	undefined output.
