I am attempting to build GCC 4.7.4, 4.8.5, 4.9.3, and 5.2.0 on HP-UX
11.31/PA. I have built GCC 4.4.6 successfully on this platform. I am
using GCC 4.4.6 as the bootstrap compiler.
My build procedure for 4.9.3 (4.7.4, 4.8.5, and 5.2.0 are similar):
$ gtar jxf /opt/src/latest/devel/gcc-4.9.3/src/gcc-4.9.3.tar.bz2
$ cd gcc-4.9.3
$ mkdir .obj
$ cd .obj

All of the above versions of GCC fail to build with the same error
above. On this platform, strtold() is defined as:
#ifdef _INCLUDE_STDC__SOURCE_199901
# if defined(__ia64)
/* pragmas needed to support -B protected */
# pragma extern strtold
# endif /* __ia64 */
# ifndef _LONG_DOUBLE
# define _LONG_DOUBLE
# if !defined(__ia64) || !defined(_PROTOTYPES) ||
defined(_LONG_DOUBLE_STRUCT)
typedef struct {
uint32_t word1, word2, word3, word4;
} long_double;
extern long_double strtold __((const char * __restrict, char ** __restrict));
# else /* !__ia64 || !_PROTOTYPES || _LONG_DOUBLE_STRUCT */
# ifdef _INCLUDE_HPUX_SOURCE
typedef long double long_double;
# endif /* _INCLUDE_HPUX_SOURCE */
extern long double strtold __((const char * __restrict, char ** __restrict));
# endif /* !__ia64 ||!_PROTOTYPES ||_LONG_DOUBLE_STRUCT */
#endif /* _LONG_DOUBLE */
#endif /* _INCLUDE_STDC__SOURCE_199901 */
and long_double is defined as:
# 547 "/opt/build/china/gcc-5.2.0/.obj/gcc/include-fixed/stdlib.h" 3 4
typedef struct {
uint32_t word1, word2, word3, word4;
} long_double;
Looks like the long double type, GFC_REAL_16, is defined in
libgfortran/kinds.h which is generated by mk-kinds-h.sh and this
defines "long double" as:
if $compile -S tmp$$.f90 > /dev/null 2>&1; then
case $k in
4) ctype="float" ; cplxtype="complex float" ; suffix="f" ;;
8) ctype="double" ; cplxtype="complex double" ; suffix="" ;;
10) ctype="long double" ; cplxtype="complex long double" ; suffix="l" ;;
16) if [ $long_double_kind -eq 10 ]; then
ctype="__float128"
cplxtype="_Complex float __attribute__((mode(TC)))"
suffix="q"
else
ctype="long double"
cplxtype="complex long double"
suffix="l"
fi ;;
*) echo "$0: Unknown type" >&2 ; exit 1 ;;
esac
What is the best way to fix this? On HP-UX 11.11/PA and 11.23/PA,
long_double is converted to "long double" by fixincludes/inclhack.def:
/*
* HP-UX long_double
*/
fix = {
hackname = hpux_long_double;
mach = "*-*-hpux10*";
mach = "*-*-hpux11.[012]*";
files = stdlib.h;
select = "extern[ \t]long_double[ \t]strtold";
bypass = "long_double_t";
sed = "/^#[ \t]*ifndef _LONG_DOUBLE/,/\\/\\* _LONG_DOUBLE \\*\\//D";
sed = "s/long_double/long double/g";
test_text = "# ifndef _LONG_DOUBLE\n"
"# define _LONG_DOUBLE\n"
" typedef struct {\n"
" unsigned int word1, word2, word3, word4;\n"
" } long_double;\n"
"# endif /* _LONG_DOUBLE */\n"
"extern long_double strtold(const char *, char **);\n";
};
Is there a reason this is not done for HP-UX 11.31?
