|
|
|
* gencode.c (MIPS_DECODE): Set UNSIGNED for multu instruction.
|
|
(process_instructions): Correct handling of nor instruction.
|
|
Correct shift count for 32 bit shift instructions. Correct sign
|
|
extension for arithmetic shifts to not shift the number of bits in
|
|
the type. Fix 64 bit multiply high word calculation. Fix 32 bit
|
|
unsigned multiply. Fix ldxc1 and friends to use coprocessor 1.
|
|
Fix madd.
|
|
* interp.c (CHECKHILO): Don't set HIACCESS, LOACCESS, or HLPC.
|
|
It's OK to have a mult follow a mult. What's not OK is to have a
|
|
mult follow an mfhi.
|
|
(Convert): Comment out incorrect rounding code.

|
|
|
|
* Makefile.in (gencode): Depend upon gencode.o, getopt.o, and
|
|
getopt1.o, rather than on gencode.c. Link objects together.
|
|
Don't link against -liberty.
|
|
(gencode.o, getopt.o, getopt1.o): New targets.

|
|
|
* gencode.c (process_instructions): Generate word64 and uword64
|
|
instead of `long long' and `unsigned long long' data types.

for SIGBUS.
|
|
* (Convert): Work around for Visual-C++ compiler bug with type
|
|
conversion.
|
|
* support.h: Make things compile under Visual-C++ by using
|

__int64 instead of `long long'. Change many refs to long long
|
|
into word64/uword64 typedefs.
