From 64485362e8de1cf93e55c3498e2af97cbf520f4b Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Wed, 21 Mar 2001 16:42:39 +0000 Subject: * frame.h (SIZEOF_FRAME_SAVED_REGS): Report an error if macro already defined. From 2000-08-25 Stephane Carrez : * stabsread.c (define_symbol): A parameter ('R'), a local ('r'), or a reference ('a') can be in a pseudo register. * infcmd.c (do_registers_info): Must take into account the pseudo registers to print their value. (registers_info): Likewise. * stack.c (frame_info): Likewise. * frame.h (SIZEOF_FRAME_SAVED_REGS): Save the pseudo registers. --- gdb/frame.h | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) (limited to 'gdb/frame.h') diff --git a/gdb/frame.h b/gdb/frame.h index 561ae27..5d98801 100644 --- a/gdb/frame.h +++ b/gdb/frame.h @@ -81,7 +81,7 @@ struct frame_info address where the sp was saved. */ /* Allocated by frame_saved_regs_zalloc () which is called / initialized by FRAME_INIT_SAVED_REGS(). */ - CORE_ADDR *saved_regs; /*NUM_REGS */ + CORE_ADDR *saved_regs; /*NUM_REGS + NUM_PSEUDO_REGS*/ #ifdef EXTRA_FRAME_INFO /* XXXX - deprecated */ @@ -114,11 +114,17 @@ enum print_what LOC_AND_ADDRESS }; -/* Allocate additional space for appendices to a struct frame_info. */ +/* Allocate additional space for appendices to a struct frame_info. + NOTE: Much of GDB's code works on the assumption that the allocated + saved_regs[] array is the size specified below.
