The old approach + didn't work for Linux 2.2 and beyond, and didn't work with recent + versions of the GNU C library. + * i386-tdep.c (LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0, + LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1): New defines. + (linux_rt_sigtramp_code): New variable. + (LINUX_RT_SIGTRAMP_LEN): New define. + (i386_linux_rt_sigtramp_start): New function. Detect start of + signal trampolines for RT signals. + (i386_linux_sigtramp): Removed. + (i386_linux_in_sigtramp): New function. + (i386_linux_sigcontext_addr): New function. Recognize the names + of the signal tranmpolines used by recent versions of the GNU C + library, and add support for RT signals. + (LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): New + defines. Moved here from config/i386/tm-linux.h. + (i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp): + Reimplement in terms of i386_linux_sigcontext_addr. + * config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Removed. + (LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): + Moved to i386-tdep.c. + (IN_SIGTRAMP): Redefine to call i386_linux_in_sigtramp. + Sat Mar 4 19:38:11 2000 Andrew Cagney <cagney@b1.cygnus.com> By: Sat Mar 4 04:08:58 2000 Alexandre Oliva <oliva@lsd.ic.unicamp.br> |
