On some architectures, the parts of math_private.h relating to the floating-point environment are in a separate file fenv_private.h included from math_private.h. As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include <fenv_private.h> and peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next <fenv_private.h>. The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of <stdbool.h>, as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/fenv_private.h: New file. Based on .... * sysdeps/aarch64/fpu/math_private.h: ... this file. All contents moved to fenv_private.h except for ... (TOINT_INTRINSICS): Kept in math_private.h. (roundtoint): Likewise. (converttoint): Likewise. * sysdeps/arm/fenv_private.h: Change multiple-include guard to [ARM_FENV_PRIVATE_H]. Include next <fenv_private.h>. * sysdeps/arm/math_private.h: Remove. * sysdeps/generic/fenv_private.h: New file. Contents moved from .... * sysdeps/generic/math_private.h: ... this file. Include <stdbool.h>. Do not include <fenv.h> or <get-rounding-mode.h>. Include <fenv_private.h>. Remove functions and macros moved to fenv_private.h. * sysdeps/i386/fpu/math_private.h: Remove. * sysdeps/mips/math_private.h: Move to .... * sysdeps/mips/fpu/fenv_private.h: ... here. Change multiple-include guard to [MIPS_FENV_PRIVATE_H]. Remove [__mips_hard_float] conditional. Include next <fenv_private.h>. * sysdeps/powerpc/fpu/fenv_private.h: Change multiple-include guard to [POWERPC_FENV_PRIVATE_H]. Include next <fenv_private.h>. * sysdeps/powerpc/fpu/math_private.h: Do not include <fenv_private.h>. * sysdeps/riscv/rvf/math_private.h: Move to .... * sysdeps/riscv/rvf/fenv_private.h: ... here. Change multiple-include guard to [RISCV_FENV_PRIVATE_H]. Include next <fenv_private.h>. * sysdeps/sparc/fpu/fenv_private.h: Change multiple-include guard to [SPARC_FENV_PRIVATE_H]. Include next <fenv_private.h>. * sysdeps/sparc/fpu/math_private.h: Remove. * sysdeps/i386/fpu/fenv_private.h: Move to .... * sysdeps/x86/fpu/fenv_private.h: ... here. Change multiple-include guard to [X86_FENV_PRIVATE_H]. Include next <fenv_private.h>. * sysdeps/x86_64/fpu/math_private.h: Do not include <sysdeps/i386/fpu/fenv_private.h>. |
