sigsetjmp/siglongjmp without saving the signal mask is faster than setjmp/longjmp on systems where the signal mask is saved. This patch uses sigsetjmp/siglongjmp without saving the signal mask if possible. PR binutils/16886 * config.in: Regenerated. * configure: Likewise. * configure.in: Check if sigsetjmp is available. * h8500-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn_h8500): Replace setjmp with OPCODES_SIGSETJMP. * i386-dis.c (dis_private): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn): Replace setjmp with OPCODES_SIGSETJMP. * ns32k-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn_ns32k): Replace setjmp with OPCODES_SIGSETJMP. * sysdep.h (OPCODES_SIGJMP_BUF): New macro. (OPCODES_SIGSETJMP): Likewise. (OPCODES_SIGLONGJMP): Likewise. * vax-dis.c (private): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn_vax): Replace setjmp with OPCODES_SIGSETJMP. * xtensa-dis.c (dis_private): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn_xtensa): Replace setjmp with OPCODES_SIGSETJMP. * z8k-dis.c(instr_data_s): Replace jmp_buf with OPCODES_SIGJMP_BUF. (fetch_data): Replace longjmp with OPCODES_SIGLONGJMP. (print_insn_z8k): Replace setjmp with OPCODES_SIGSETJMP.

Well, some generic common stuff is done here too, like including
|
|
ansidecl.h. That's because the .h files in bfd/hosts files I'm
|
|
trying to replace often did that. If it can be dropped from this

file (check in a non-ANSI environment!), it should be. */
