From 23e60e7a4ea772eabb6ae4788913e228763755cf Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Fri, 17 Aug 2018 08:54:26 +0100 Subject: [PATCH] gdb: Extend the trad-frame API Adds two new functions to the trad-frame API and update the internals of trad-frame to use the new functions. These functions will be used in later commits. gdb/ChangeLog: * trad-frame.h (trad_frame_set_realreg): Declare. (trad_frame_set_addr): Declare. * trad-frame.c (trad_frame_set_realreg): Define new function. (trad_frame_set_addr): Define new function. (trad_frame_set_reg_realreg): Use new function. (trad_frame_set_reg_addr): Use new function. --- gdb/ChangeLog | 9 +++++++++ gdb/trad-frame.c | 25 ++++++++++++++++++++++--- gdb/trad-frame.h | 8 ++++++++ 3 files changed, 39 insertions(+), 3 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 128c0e85973..446fa22a0f2 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2018-09-03 Andrew Burgess + + * trad-frame.h (trad_frame_set_realreg): Declare. + (trad_frame_set_addr): Declare. + * trad-frame.c (trad_frame_set_realreg): Define new function. + (trad_frame_set_addr): Define new function. + (trad_frame_set_reg_realreg): Use new function. + (trad_frame_set_reg_addr): Use new function. + 2018-09-01 Keith Seitz * compile/compile-cplus-types.c (compile_cplus_debug_output_1): Use diff --git a/gdb/trad-frame.c b/gdb/trad-frame.c index a6e24158279..fd9f24084dc 100644 --- a/gdb/trad-frame.c +++ b/gdb/trad-frame.c @@ -105,6 +105,26 @@ trad_frame_set_value (struct trad_frame_saved_reg this_saved_regs[], this_saved_regs[regnum].addr = val; } +/* See trad-frame.h. */ + +void +trad_frame_set_realreg (struct trad_frame_saved_reg this_saved_regs[], + int regnum, int realreg) +{ + this_saved_regs[regnum].realreg = realreg; + this_saved_regs[regnum].addr = -1; +} + +/* See trad-frame.h. */ + +void +trad_frame_set_addr (struct trad_frame_saved_reg this_saved_regs[], + int regnum, CORE_ADDR addr) +{ + this_saved_regs[regnum].realreg = regnum; + this_saved_regs[regnum].addr = addr; +} + void trad_frame_set_reg_value (struct trad_frame_cache *this_trad_cache, int regnum, LONGEST val) @@ -118,15 +138,14 @@ void trad_frame_set_reg_realreg (struct trad_frame_cache *this_trad_cache, int regnum, int realreg) { - this_trad_cache->prev_regs[regnum].realreg = realreg; - this_trad_cache->prev_regs[regnum].addr = -1; + trad_frame_set_realreg (this_trad_cache->prev_regs, regnum, realreg); } void trad_frame_set_reg_addr (struct trad_frame_cache *this_trad_cache, int regnum, CORE_ADDR addr) { - this_trad_cache->prev_regs[regnum].addr = addr; + trad_frame_set_addr (this_trad_cache->prev_regs, regnum, addr); } void diff --git a/gdb/trad-frame.h b/gdb/trad-frame.h index f7ec43cc80c..a11a2c29c9c 100644 --- a/gdb/trad-frame.h +++ b/gdb/trad-frame.h @@ -88,6 +88,14 @@ struct trad_frame_saved_reg void trad_frame_set_value (struct trad_frame_saved_reg this_saved_regs[], int regnum, LONGEST val); +/* Encode REGNUM is in REALREG in the trad-frame. */ +void trad_frame_set_realreg (struct trad_frame_saved_reg this_saved_regs[], + int regnum, int realreg); + +/* Encode REGNUM is at address ADDR in the trad-frame. */ +void trad_frame_set_addr (struct trad_frame_saved_reg this_trad_cache[], + int regnum, CORE_ADDR addr); + /* Mark REGNUM as unknown. */ void trad_frame_set_unknown (struct trad_frame_saved_reg this_saved_regs[], int regnum); -- 2.30.2
