XMAME 0.67.1

System #2 Slightly better CPU for enjoying xmame

Software
Both systems began as vanilla RedHat 6.2 boxes, but packages have been heavily recompiled for speed and updated with latest security enhancements. Highlights as follows.

No lectures on obsolescence, please. I know full-well the evils of old-school XFree et. al. Newer systems will be forthcoming on this list soon enough. K6-3+ is a great overclocker, but it won't cut the mustard for kinst. :)

xmame Compile Options

CFLAGS = -O2 -Wall -Wno-unused -march=i586 -pipe -fomit-frame-pointer -fstrict-aliasing -fstrength-reduce -ffast-math

CFLAGS = -O3 -pipe -mcpu=pentium -march=pentium -Wall -Wno-unused -funroll-loops -fstrength-reduce -fomit-frame-pointer -ffast-math -malign-functions=2 -malign-jumps=2 -malign-loops=2

PROBLEM #1

src/sound/multipcm.c does not compile!

EXPLANATION

Some gcc versions are evidently more picky than others about the ordering of declarations and assignments. gcc 2.91.66 refuses to compile multipcm.c as a result.

FILES AFFECTED

The following files need fixes.

FIXES

Below are the details of how to fix the file.

multipcm.c

The following lines need to be swapped.

PROBLEM #2

src/vidhrdw/seta2.c does not compile!

EXPLANATION

Some gcc versions are evidently more picky than others about the ordering of declarations and assignments. gcc 2.91.66 refuses to compile seta2.c as a result. This file changed from 0.66.2. sizex and sizey are now assigned before x and y variables are declared. This causes compile to break on old gcc versions.

PROBLEM #3

src/drivers/dynax.c does not compile!

EXPLANATION

Some gcc versions are evidently more picky than others about the ordering of declarations and assignments. gcc 2.91.66 refuses to compile dynax.c as a result. This file changed from 0.66.2. For "maya" a for loop occurs before *gfx and i are declared. This causes compile to break on old gcc versions.
