Add proper float formatting to vuprintf

2018-02-09T02:36:20+00:00

Wanted to see how gnarly it is to do.

Big number handling could be done with better algorithms
since it can get a bit slow with large integers or tiny
fractions with many lead zeros when only a few digits are
needed.

Anyway, it supports %e, %E, %f, %F, %g and %G. No %a or long
double support seems warranted at the moment.

Assumes IEEE 754 double format but it's laid out to be able to
replace a function to handle others if needed.

Tested in a driver program that has a duplicate vuprintf and
the content was pasted in once it looked sound enough to put
up a patch.

Enable semaphore objects unconditionally

2018-01-05T22:47:03+00:00

This is a prerequisite for duke3d running on monochrome targets. It should
probably be made more fine-grained before it is merged, since I'm pretty
sure there were good reasons to limit it as before.

Revert "Support floating-point formatting"

2017-12-25T00:22:17+00:00

This reverts commit 01c6dcf6c7b9bb1ad2fa0450f99bacc5f3d3e04b.

The hack isn't used in duke, so having it is redundant.

Port of Duke Nukem 3D

2017-12-24T02:01:26+00:00

This ports Fabien Sanglard's Chocolate Duke to run on a version of SDL
for Rockbox.

Support floating-point formatting

2017-12-24T01:55:02+00:00

This is just a quick and dirty way to get %f formatting to work for
some games. It works.

stdio compat layer for plugins

2017-12-24T01:54:56+00:00

This is attempt to simplify porting programs to rockbox (as plugins).
Currently this compat layer implements:
fopen(), fclose(), fflush(), fread(), fwrite(), fseek(), fseeko(),
ftell(), ftello(), fgetc(), ungetc(), fputc(), fgets(), clearerr(),
ferror(), feof(), fprintf()

In order to use it you need to include in ported sources
"lib/stdio_compat.h"

Get voice event out of playback.c

2017-12-13T01:28:56+00:00

Purpose: A step in removing all voice references from playback code
and prelude to other changes.

Playback: Move internal track list onto buffer

2017-12-09T22:05:59+00:00

Does away the statically-allocated track list which frees quite
a fair amount of in-RAM size.

There's no compile-time hard track limit.

Recommended TODO (but not right away): Have data small enough use
the handle structure as its buffer data area. Almost the entire
handle structure is unused for simple allocations without any
associated filesystem path.

Add a small 32-byte write buffer to fdprintf.

2017-11-28T14:01:17+00:00

Avoids a call to write() for every output character. It doesn't
need to be very large to have a great effect on speed and realize
most of the potential.
