xmame 0.106 (need some help with MIPSpro)

[gijoe77]

These are my preferred mipspro optimization options:

Code: Select all

-O3 -mips4 -TARG:platform=IP35:proc=r16000 -OPT:Olimit=0:roundoff=3:alias=TYPED -INLINE

sweet! thanks mate, gonna plug these in and see where i land!

don't unless you know what each of them does. you might want something else or have a different machine or a different compiler version etc.

eh.. this part here:

-

Code: Select all

OPT:Olimit=0:roundoff=3:alias=TYPED

kinda lost me to be honest

seems you've not yet checked the manpage. there you'd find nice stuff like:

Olimit=n
Specifies that any routine bigger than n should not be
optimized. If -O2 or greater is in effect and a routine is so
big that the compile speed may be slow, the compiler generates
a message indicating the Olimit value that is needed to
optimize. You can recompile with that value of n. The
-OPT:Olimit=0 option is not recommended for general use.

not gonna paste the roundoff and alias parts

Since we are talking about mame this should be no problem.

Code: Select all

OPT:Olimit=0:roundoff=3:alias=TYPED

man opt and man inline will explain the options.

ok, I just compiled a new xmame.x11 v0.106 using MIPSpro and the following CFLAGS:

Code: Select all

CFLAGS = -woffall -O3 -mips4 -TARG:platform=IP35:proc=r16000 -OPT:Olimit=0:roundoff=3:alias=TYPED -INLINE

I added

Code: Select all

-LNO:opt=0

only for scramble.c to compile (wasn't able to figure out any other way to get LNO not to die on scramble.c)

I attached the makefile and binary if anyone wants to give it a spin, its an easy 10 more fps than the gcc build for me. I can build a generic mips4 binary if anyone is interested

I'm still trying to figure out the m68k -IPA ld shizm

I don't understand most of the conversation but well done none the less! It never ceases to amaze me how much you guys can do with these systems.
