Bill Schmidt	32e9c6465b	[PPC] Adjust some PowerPC tests to account for presence/absence of VSX Patch by Bill Seurer; committed on his behalf. These test cases generate slightly different code sequences when VSX is activated and thus fail. The update turns off VSX explicitly for the existing checks and then adds a second set of checks for most of them that test the VSX instruction output. llvm-svn: 220019	2014-10-17 01:41:22 +00:00
Hal Finkel	e4eb78188c	Add ExpandFloatOp_FCOPYSIGN to handle ppcf128-related expansions We had previously been asserting when faced with a FCOPYSIGN f64, ppcf128 node because there was no way to expand the FCOPYSIGN node. Because ppcf128 is the sum of two doubles, and the first double must have the larger magnitude, we can take the sign from the first double. As a result, in addition to fixing the crash, this is also an optimization. llvm-svn: 188655	2013-08-19 06:55:37 +00:00

Patch by Bill Seurer; committed on his behalf.

These test cases generate slightly different code sequences when VSX
is activated and thus fail. The update turns off VSX explicitly for
the existing checks and then adds a second set of checks for most of
them that test the VSX instruction output.

Add ExpandFloatOp_FCOPYSIGN to handle ppcf128-related expansions

We had previously been asserting when faced with a FCOPYSIGN f64, ppcf128 node
because there was no way to expand the FCOPYSIGN node. Because ppcf128 is the
sum of two doubles, and the first double must have the larger magnitude, we
can take the sign from the first double. As a result, in addition to fixing the
crash, this is also an optimization.
