(LINUX_SIGTRAMP_INSN0, LINUX_SIGTRAMP_OFFSET0, LINUX_SIGTRAMP_INSN1, LINUX_SIGTRAMP_OFFSET1, LINUX_SIGTRAMP_INSN2, LINUX_SIGTRAMP_OFFSET2, linux_sigtramp_code, LINUX_SIGTRAMP_LEN, i386_linux_sigtramp_start, LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0, LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1, linux_rt_sigtramp_code, LINUX_RT_SIGTRAMP_LEN, i386_linux_rt_sigtramp_start, i386_linux_in_sigtramp, i386_linux_sigcontext_addr, LINUX_SIGCONTEXT_PC_OFFSET, i386_linux_sigtramp_saved_pc, LINUX_SIGCONTEXT_SP_OFFSET, i386_linux_sigtramp_saved_sp): Deleted. Folks rightly pointed out that these are target-dependent, and useful in non-native configurations. Moved to... * i386-linux-tdep.c: ... Here, a new file. * Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c. (i386-linux-tdep.o): New rule.

Print an error at compile time if we are to use select, but FD_SET is not available. (SELECT_MASK, NBBY, FD_SETSIZE, NFDBITS, MASK_SIZE): Define only if HAVE_POLL is not defined and NO_FD_SET is defined. (create_file_handler) [!HAVE_POLL]: Use FD_SET and FD_CLR. (delete_file_handler) [!HAVE_POLL]: Use FD_CLR and FD_ISSET. (gdb_wait_for_event) [!HAVE_POLL]: Copy fd_set sets directly instead of using memcpy and memset. Use FD_ISSET. * config/i386/xm-go32.h (fd_mask): Remove typedef.	27 years ago
Eli Zaretskii	ded59a1e28	Support for building GDB with DJGPP, and running the test suite on it: * config/djgpp/djconfig.sh: New file. * config/djgpp/config.sed: New file. * config/djgpp/README: New file. * config/djgpp/fnchange.lst: New file. * config/djgpp/djcheck.sh: New file.	27 years ago

These all implement Linux-specific signal trampoline detection, and should be moved to... * i386-linux-nat.c: ... here. * config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define this any more, since we're not enabling OS-specific code in a OS-independent file.	27 years ago
Mark Kettenis	4cc2418890	2000-03-08 Mark Kettenis <kettenis@gnu.org> * i386-tdep.c (i386_linux_saved_pc_after_call): New function. * config/i386/tm-linux.h (SAVED_PC_AFTER_CALL): Define to call i386_linux_saved_pc_after_call.	27 years ago

(PTRACE_XFER_TYPE, CANNOT_FETCH_REGISTER, fetch_register, old_fetch_inferior_registers, CANNOT_STORE_REGISTER, store_register, old_store_inferior_registers): Copied over from `inptrace.c' as a temporary measure. (fetch_regs, store_regs, fetch_fpregs, store_fpregs): Conditionalize on HAVE_PTRACE_GETREGS. Define stubs if HAVE_PTRACE_GETREGS isn't defined. (fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails with EIO. (fetch_inferior_registers, store_inferior_registers): Fall back on the method use in `infptrace.c' (by calling old_fetch_inferior_registers and old_store_inferior_registers) if `have_ptrace_getregs' isn't set.	27 years ago
Mark Kettenis	45a816d93e	2000-03-04 Mark Kettenis <kettenis@gnu.org> Fix support for Linux/i386 signal trampolines. 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.	27 years ago
