Otherwise, + operations requiring an implicit call to malloc() will fail. + + * infrun.c (wait_for_inferior): The criterion to detect entering a + sigtramp handler is now: (a) the current pc is inside a sigtramp + handler, (b) the previous pc is not in a sigtramp handler, and (c) + the current stack pointer is "inner" than the old one. Condition + (c) is new to avoid mistaking a return from a signal handler into + sigtramp as a new sigtramp invocation. + + * dcache.c (struct dcache_block): Declare addr as CORE_ADDR. An + int may not be big enough to hold an address. + (dcache_hit): Ditto. + (dcache_peek_byte): Fix indentation. + + * configure.in (alpha-*-linux*): Add target. + * configure: Rebuild + + * config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro. + (SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto. + (DYNAMIC_SIGTRAMP_OFFSET): Ditto. + (SIGCONTEXT_ADDR): Ditto. + (FRAME_PAST_SIGTRAMP_FRAME): Ditto. + + * config/alpha/alpha-linux.mh: New file. + * config/alpha/alpha-linux.mt: Ditto. + * config/alpha/nm-linux.h: Ditto. + * config/alpha/tm-alphalinux.h: Ditto. + * config/alpha/xm-alphalinux.h: Ditto. + * config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h. + * config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to + xm-alphaosf.h. + * config/alpha/alpha-osf2.mh: Ditto. + + * blockframe.c (find_pc_partial_function): Pass PC to + SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems + that detect sigtramp code via designated code sequences (as is the + case for Linux/Alpha, for example). + + * config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END + to ignore new PC argument. + * config/m68k/tm-hp300bsd.h: Ditto. + * config/vax/tm-vax.h: Ditto. + + * alpha-tdep.c (alpha_linux_sigtramp_offset): New function. + (alpha_osf_skip_sigtramp_frame): Ditto. + (push_sigtramp_desc): Ditto. + (alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract + sigcontext address from frame. + (alpha_saved_pc_after_call): When in sigtramp, use + alpha_frame_saved_pc() instead of read-register(). + (after_prologue): When inside a dynamically generated sigtramp + function, there is no prologue, so return address of first + instruction. + (alpha_in_prologue): Fix typo in comment. + (find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine + whether we're inside a dynamicaly generated sigtramp function. If + so, create and push and appropriate procedure descriptor. + (alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain + the frame past a sigtramp frame (if the current frame is indeed a + sigtramp function). + (init_extra_frame_info): Don't read next frame register off of + stack-pointer when inside a dynamiccaly generated sigtramp. + (alpha_pop_frame): Also unlink and destroy procedure descriptors + created for dynamically generated sigtramp functions. + + * alpha-nat.c: When compiling under Linux, include <asm/reg.h> and + <alpha/ptrace.h> instead of <machine/reg.h> + Thu May 23 15:13:56 1996 Jeffrey A Law (law@cygnus.com) * h8300-tdep.c (IS_PUSH): Refine. |
