From 89dea5aa55a43f4afa567c1d3a5fd7b0470abdd4 Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Sun, 18 Feb 2001 07:22:17 +0000 Subject: * go32-nat.c: Include i387-nat.h. (fetch_register): New function, uses some of the guts of go32_fetch_registers and i387_supply_register. (go32_fetch_registers): Most of the code moved into fetch_register. Use i387_supply_fsave. (store_register): Use i387_fill_fsave instead of custom code. (go32_store_registers): Use i387_fill_fsave. * Makefile.in (go32-nat.o): Depend on i387-nat.h. * config/i386/go32.mh (NATDEPFILES): Add i387-nat.o. --- gdb/ChangeLog | 12 ++++++++ gdb/Makefile.in | 2 +- gdb/config/i386/go32.mh | 2 +- gdb/go32-nat.c | 82 ++++++++++++++++--------------------------------- 4 files changed, 40 insertions(+), 58 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2115929..3623e02 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,17 @@ 2001-02-18 Eli Zaretskii + * go32-nat.c: Include i387-nat.h. + (fetch_register): New function, uses some of the guts of + go32_fetch_registers and calls i387_supply_register. + (go32_fetch_registers): Most of the code moved into + fetch_register.
