- Subject: patch to fix __builtin_powi failure on apple-ppc-darwin (revised)
Following DejaGnu test fails when run using darwin's mixed mode
(-mcpu=G5).
FAIL: gcc.dg/pr19402-2.c execution test
This is because word_mode is used in setting up the call to
__builtin_powi.
Declaration for these functions are in libgcc2.h.
extern SFtype __powisf2 (SFtype, Wtype);
extern DFtype __powidf2 (DFtype, Wtype);
Wtype can be anything from a DItype to QItype and its size depends on
setting of MIN_UNITS_PER_WORD.
There is no guarantee that word_mode's size matches MIN_UNITS_PER_WORD
for all compilation
modes. For example, for apple's mixed mode (-mcpu=G5), former is 64
while latter is 32. This
patch uses a new type mode, instead of word_mode to be used in setting
up 2nd argument in call
to __builtin_powi. This mode is in lock-step with Wtype. Also, this
same mode has been used
in setting up the call to __builtin_ffs. Bootstrap is in progress.
OK for mainline?

* builtins.c (expand_builtin_powi): Fix mode of
2nd argument to match that of Wtype.
