Summary: bootstrap error with math.h after fixes 5200-01
Product: gcc
Version: 3.3
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: bootstrap
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: kminola at eng dot umd dot edu
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: powerpc-ibm-aix5.2.0.0
GCC host triplet: powerpc-ibm-aix5.2.0.0
GCC target triplet: powerpc-ibm-aix5.2.0.0
After install of AIX 5.2 maintenance fixes (5200-01), gcc-3.3 no longer
bootstraps. (gcc-3.3 did bootstrap on AIX 5.2 before fixes installed.)
Bootstrap error is

make[2]: *** [genautomata.o] Error 1
Error is caused by changes in macro fpclassify() in math.h
that fixincludes now no longer handles correctly.
Previously fpclassify() in math.h was defined to be
----------------------------------------------------
#ifndef _LONGDOUBLE128
#define fpclassify(__x) \
((sizeof(__x) == sizeof(float)) ? _classf((double) __x) : _class(__x))
[... irrelevant stuff deleted ...]
#else
#define fpclassify(__x) \
((sizeof(__x) == sizeof(float)) ? _classf(__x) : \
(sizeof(__x) == sizeof(double)) ? _class(__x) : \
? _classl128(__x))
---------------------------------------------------------------
Now fpclassify() is
---------------------------------------------------------------
#ifndef __LONGDOUBLE128
#define fpclassify(__x) \
(sizeof(__x) == sizeof(float) ? \
((_classf((double)__x) == FP_SNAN) || (_classf((double)__x) == FP_QNAN)
? \
FP_QNAN : \
(_classf((double) __x) & 0x00000001 ? \
_classf((double) __x) - 1 : \
_classf((double) __x)) ) : \
((class(__x) == FP_SNAN) || (class(__x) == FP_QNAN) ? \
FP_QNAN : \
(class(__x) & 0x00000001 ? \
_class(__x) - 1 : \
_class(__x))))
[...irrelevant stuff deleted ...]
#else
#define fpclassify(__x) \
(sizeof(__x) == sizeof(float) ? \
((_classf((double)__x) == FP_SNAN) || (_classf((double)__x) == FP_QNAN)
? \
FP_QNAN : \
(_classf((double) __x) & 0x00000001 ? \
_classf((double) __x) - 1 : \
_classf((double) __x))) :\
(sizeof(__x) == sizeof(double) ? \
((class(__x) == FP_SNAN) || (class(__x) == FP_QNAN) ? \
FP_QNAN : \
(class(__x) & 0x00000001 ? \
_class(__x) - 1 : \
_class(__x))) :\
((_classl128(__x) == FP_SNAN) || (_classl128(__x) == FP_QNAN) ? \
FP_QNAN: \
(_classl128(__x) & 0x00000001 ? \
_classl128(__x) - 1 : \
_classl128(__x)))))
----------------------------------------------------------------------
The bootstrap error is caused by the fact that fixincludes surrounds
the four occurrances of "class" with
#ifndef __cplusplus
#endif
For example:
#define fpclassify(__x) \
(sizeof(__x) == sizeof(float) ? \
((_classf((double)__x) == FP_SNAN) || (_classf((double)__x) == FP_QNAN)
?
\
FP_QNAN : \
(_classf((double) __x) & 0x00000001 ? \
_classf((double) __x) - 1 : \
_classf((double) __x)) ) : \
#ifndef __cplusplus
((class(__x) == FP_SNAN) || (class(__x) == FP_QNAN) ? \
#endif
FP_QNAN : \
#ifndef __cplusplus
(class(__x) & 0x00000001 ? \
#endif
_class(__x) - 1 : \
_class(__x))))
Possible fix - if each of the occurances of "class" is changed to
"_class", gcc-3.3 will bootstrap.

While GCC fixincludes could work around this, it really is an AIX problem. This
has been opened as a defect against AIX 5.2 and will be fixed by IBM APAR
IY46553. It should be avaliable from IBM Customer Support website in a few
weeks (I'll add the PTF number when I find out) and should appear in the next
maintenance release.
