Bug ID: 57391
Summary: [4.9 Regression] ICE compiling AIX math.h caused by PR
c++/56930
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
The patch for PR c++/56930 breaks bootstrap on AIX when building libstdc++. I
now receive the following error message:
/tmp/20130524/gcc/include-fixed/math.h: In function 'long double
fmal(long double, long double, long double)':
/tmp/20130524/gcc/include-fixed/math.h:879:135: internal compiler
error: unexpected expression '#'fma_expr' not supported by
dump_expr#<expression error>' of kind fma_expr
inline long double fmal(long double __x, long double __y, long double
__z) { return fma((double) (__x), (double) (__y), (double) (__z)); }
When not using long double 128, AIX math.h provides a number of
definitions, including
inline long double fmal(long double __x, long double __y, long double __z)
{ return fma((double) (__x), (double) (__y), (double) (__z)); }

removes the ICE.
