This commit creates a new file, common/gdb_setjmp.h, to hold some portability macros for setjmp/longjmp et al. that are used by the exceptions subsystem and by the demangler crash catcher. gdb/ChangeLog: * common/gdb_setjmp.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add common/gdb_setjmp.h. * configure.ac: Move sigsetjmp check... * common/common.m4: ...here. * configure: Regenerate. * cp-support.c (SIGJMP_BUF): Delete. (SIGSETJMP): Likewise. (SIGLONGJMP): Likewise. * exceptions.h (gdb_setjmp.h): Include. (setjmp.h): Do not include. (EXCEPTIONS_SIGJMP_BUF): Delete. (EXCEPTIONS_SIGSETJMP): Likewise. (EXCEPTIONS_SIGLONGJMP): Likewise. Replace all uses of EXCEPTIONS_SIG* macros with SIG* macros from gdb_setjmp.h. * exceptions.c: Likewise. gdb/gdbserver/ChangeLog: * config.in: Regenerate. * configure: Likewise.
