From ad146de70ec85c70a680bb4817f1d9e9f3bc7fd6 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 4 Nov 2004 23:37:44 +0000 Subject: * sysdeps/unix/sysv/linux/x86_64/sys/procfs.h [__WORDSIZE == 32] (elf_fpxregset_t): New type. (struct elf_prpsinfo): If __WORDSIZE == 32, change pr_[ug]id type to unsigned short int. * sysdeps/unix/sysv/linux/x86_64/sys/user.h (struct user_fpregs_struct): Fix comment. * sysdeps/i386/fpu/bits/mathdef.h (float_t, double_t): If __FLOAT_EVAL_METHOD__ is defined and 0, typedef to float resp. double. * sysdeps/x86_64/fpu/bits/mathdef.h: Include bits/wordsize.h. (float_t, double_t): If -m32 and not -mfpmath=sse, typedef to long double. * sysdeps/x86_64/fpu/bits/fenv.h: Include bits/wordsize.h. (fenv_t): Remove __mxcsr field for -m32. --- sysdeps/i386/fpu/bits/mathdef.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'sysdeps/i386') diff --git a/sysdeps/i386/fpu/bits/mathdef.h b/sysdeps/i386/fpu/bits/mathdef.h index d5fe79fbd1..ec42ed5df9 100644 --- a/sysdeps/i386/fpu/bits/mathdef.h +++ b/sysdeps/i386/fpu/bits/mathdef.h @@ -23,6 +23,13 @@ #if defined __USE_ISOC99 && defined _MATH_H && !defined _MATH_H_MATHDEF # define _MATH_H_MATHDEF 1 +# if defined __FLT_EVAL_METHOD__ && __FLT_EVAL_METHOD__ == 0 +/* When using -mfpmath=sse, values are computed with the precission of the + used type. */ +typedef float float_t; /* `float' expressions are evaluated as `float'. */ +typedef double double_t; /* `double' expressions are evaluated as + `double'. */ +# else /* The ix87 FPUs evaluate all values in the 80 bit floating-point format which is also available for the user as `long double'.
