m68k bits/mathinline.h declares various functions with const attributes. These are inappropriate for functions that have results depending on the rounding mode; the machine-independent bits/mathcalls.h only uses const attributes for a very few functions with no rounding mode dependence, and the m68k header should do likewise. GCC uses pure for such functions with -frounding-math, resulting in GCC mainline warning for conflicts with between the header and the built-in attributes and glibc failing to build for m68k with GCC mainline. This patch fixes the attributes to avoid using const except when bits/mathcalls.h does so. (There are a few functions where maybe bits/mathcalls.h could do so but doesn't, but keeping the headers in sync in this regard seems to be the safe approach.) Tested compilation with build-many-glibcs.py with GCC mainline. [BZ #22631] * sysdeps/m68k/m680x0/fpu/bits/mathinline.h (__m81_defun): Add argument for attrubutes. All callers changed. (__inline_mathop1): Likewise. All callers changed. (__inline_mathop): Likewise. All callers changed. [__USE_MISC] (scalbn): Use __inline_forward instead of __inline_forward_c. [__USE_ISOC99] (scalbln): Likewise. [__USE_ISOC99] (nearbyint): Likewise. [__USE_ISOC99] (lrint): Likewise. [__USE_MISC] (scalbnf): Likewise. [__USE_ISOC99] (scalblnf): Likewise. [__USE_ISOC99] (nearbyintf): Likewise. [__USE_ISOC99] (lrintf): Likewise. [__USE_MISC] (scalbnl): Likewise. [__USE_ISOC99] (scalblnl): Likewise. [__USE_ISOC99] (nearbyintl): Likewise. [__USE_ISOC99] (lrintl): Likewise. * sysdeps/m68k/m680x0/fpu/mathimpl.h: All callers of __inline_mathop and __m81_defun changed. |
