Verify that sizes, alignments and field offsets of jmp_buf as well as sigjmp_buf are unchanged regardless how struct __jmp_buf_tag is defined. Since jmp_buf is target specific, jmp_buf-macros.h is added for each Linux target. A new target must provides its own jmp_buf-macros.h. TODO: Hurd needs to provide a jmp_buf-macros.h. Tested with build-many-glibcs.py. * include/setjmp.h [!_ISOMAC]: Include <stddef.h> and <jmp_buf-macros.h>. [!_ISOMAC] (STR_HELPER): New. [!_ISOMAC] (STR): Likewise. [!_ISOMAC] (TEST_SIZE): Likewise. [!_ISOMAC] (TEST_ALIGN): Likewise. [!_ISOMAC] (TEST_OFFSET): Likewise. [!_ISOMAC] Add _Static_assert to check sizes, alignments and field offsets of jmp_buf as well as sigjmp_buf. * sysdeps/unix/sysv/linux/aarch64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/alpha/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/arm/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/hppa/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/i386/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/ia64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/m68k/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/nios2/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/sh/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/jmp_buf-macros.h: Likewise.
