I'm trying to bootstrap gcc-3.4.3 on HP-UX 11.23/IA-64. I'm bootstrapping with the HP C compiler. The system has patch PHSS_33351 installed. The tail of /usr/include/math.h: inline int sqr(int __x) {return(__x*__x);} inline double sqr(double __x) {return(__x*__x);}# ifndef _STDLIB_INCLUDED inline int abs(int __d) { return (__d>0)?__d:-__d; }# endif /* _STDLIB_INCLUDED */ inline double abs(double __d) { return fabs(__d); } inline double pow(double __d,int __expon) { return pow(__d,(double)__expon); }#endif#endif /* _MATH_INCLUDED */The tail of math.h after fixinc: inline double sqr(double __x) {return(__x*__x);}# ifndef _STDLIB_INCLUDED inline int abs(int __d) { return (__d>0)?__d:-__d; }# endif /* _STDLIB_INCLUDED */#ifndef __GNUC__ inline double abs(double __d) { return fabs(__d); } inline double pow(double __d,int __expon) { return pow(__d,(double)__expon); }#endif#endif /* _MATH_INCLUDED */Looking at inclhack.def, sco_math seems to be the cause of this. I replaced 'inline double abs' in select of sco_math with 'inline double _abs' and the #ifndef __GNUC__ wasn't included in the new math.h.Comment 1Andrew Pinski 2005-11-06 00:24:39 UTC I thought this was fixed in 3.4.4. Comment 2The Written Word 2005-11-06 00:45:01 UTC I'm using the version of inclhack.def from gcc-3_4-branch. I looked at the changes inhttp://gcc.gnu.org/viewcvs/branches/gcc-3_4-branch/gcc/fixinc/inclhack.def?rev=100333&view=log and don't see anything relating to this.Looking at the latest inclhack.def from gcc-3_4-branch, this sed line in sco_math is causing the problem: sed = "/extern \"C\\+\\+\"/N;" "/inline double abs/i\\\n" "#ifndef __GNUC__\n";I have no idea what math.h looks like on SCO so I have no idea how to fix. Why don't we restrict sco_math to some mach="*sco*"? Comment 3Steve Ellcey 2005-11-07 18:26:51 UTC It looks like this is fixed on the mainline and on the 4.0 branch by the addition ofbypass = "__GNUG__";This patch was done in revision 90550 by jsm28. We should do this for the 3.4 branch as well. |
