From: John Metzler Date: Fri, 10 Apr 1998 17:42:12 +0000 (+0000) Subject: Fri Apr 10 10:35:35 1998 John Metzler X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=6aeec893aa43455416570c80226389702582f970;p=deliverable%2Fbinutils-gdb.git Fri Apr 10 10:35:35 1998 John Metzler * mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of bit pattern interpretations. mips_fetch_instruction does not work for 16 bit instructions. Some confusion remains about sign extension in backward branches. (mips32_relative_offset): Sign extension (mips32_next_pc): Major debugging, bit pattern interpretation (print_unpack): debugging printf (fetch_mips_16): new funtion, key on PC low bit, not symbol table (mips16_next_16): Initial major debugging of this function. Lots of bit pattern mistakes. (mips_next_pc): key on low bit of PC, not symbol table. * symfile.c(generic_load) : Added a download verification which reads back the loade code. Download chunk size is now a defined macro. Fixed a bug in which downloading slips into loading one byte at a time. Lower level functions in monitor.c can load long sequences of bytes and make use of these fixups. Referencing bfd-start_address directly was incorrectly getting zero for start. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b7ae2aa697..5eb1138345 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,23 @@ +Fri Apr 10 10:35:35 1998 John Metzler + + * mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of + bit pattern interpretations. mips_fetch_instruction does not work + for 16 bit instructions.
