From 9391c9977e934749cd973dd55cde6df7f787b6ec Mon Sep 17 00:00:00 2001 From: Fred Fish Date: Sun, 26 May 1996 21:41:40 +0000 Subject: Changes from: David Mosberger-Tang * NEWS: Add Alpha Linux as a new native configuration. * mdebugread.c (parse_symbol): When we find a malloc() symbol with return type VOID, assume no debugging info is available for that object file and patch the return value into VOID *. 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 and instead of --- gdb/dcache.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'gdb/dcache.c') diff --git a/gdb/dcache.c b/gdb/dcache.c index f110a0c0..60caa29 100644 --- a/gdb/dcache.c +++ b/gdb/dcache.c @@ -111,7 +111,7 @@ struct dcache_block { struct dcache_block *p; /* next in list */ - unsigned int addr; /* Address for which data is recorded. */ + CORE_ADDR addr; /* Address for which data is recorded. */ char data[LINE_SIZE]; /* bytes at given address */ unsigned char state[LINE_SIZE]; /* what state the data is in */ @@ -155,7 +155,7 @@ static int dcache_peek_byte PARAMS ((DCACHE *dcache, CORE_ADDR addr, char *ptr)); static struct dcache_block * -dcache_hit PARAMS ((DCACHE *dcache, unsigned int addr)); +dcache_hit PARAMS ((DCACHE *dcache, CORE_ADDR addr)); static int dcache_write_line PARAMS ((DCACHE *dcache,struct dcache_block *db)); @@ -207,7 +207,7 @@ dcache_flush (dcache) static struct dcache_block * dcache_hit (dcache, addr) DCACHE *dcache; - unsigned int addr; + CORE_ADDR addr; { register struct dcache_block *db; @@ -338,7 +338,7 @@ dcache_peek_byte (dcache, addr, ptr) else db = dcache_alloc (dcache); immediate_quit++; - db->addr = MASK (addr); + db->addr = MASK (addr); while (done < LINE_SIZE) { int try = -- cgit v1.1
