3f0f9188ed Fixed bug #741
The thread ID is an unsigned long so it can hold pthread_t so people can do naughty things with it.

I'm going to be adding additional useful thread API functions, but this should prevent crashes in people's existing code on 64-bit architectures.

Betreff: [SDL] [PATCH] Make static variables const
Datum: Tue, 19 May 2009 19:45:37 +0200

Hi,

this is a set of simple changes which make some of SDL's internal static
arrays constant. The purpose is to shrink the number of write-able
static bytes and thus increase the number of memory pages shared between
SDL applications.

The patch set is against trunk@4513. Each of the attached patch files is
specific to a sub-system. The set is completed by a second mail, because
of the list's 40 KiB limit.

The files readelf-r4513.txt and readelf-const-patch.txt where made by
calling 'readelf -S libSDL.so'. They show the difference in ELF sections
without and with the patch. Some numbers measured on my x86-64:

The size of the write-able data section decreased considerably. Some
entries became const-after-relocation, while most of its content went
straight into the read-only data section.

Best regards, Thomas

ad347d4a12 Fixed Bugzilla bug #205
Removed SDL_KillThread() from the API, as it isn't safe on many platforms.

Subject: Re: Updating SDL for RISC OS

I've attached a zip file with three diffs to get SDL to build on RISC OS.

configure.in.diff and makedeps.sh.diff have been modified so that they
can build the assembler file in video/riscos. You may want to double
check these as I don't know a lot about unix shell programming.
(I've tested them cross-compiling on cygwin).

sdlsysthread.diff is the changes required to SDL_systhread.c for RISC
OS. As you suspected with these changes in place you can delete the
RISC OS specific threading code in thread/riscos.

I've also renamed SDL_riscosASM.s to SDL_riscosASM.S, but I'm never
quite sure how to rename files in CVS, so if you could to this it would
be appreciated.

c36118165e Use consistent identifiers for the various platforms we support.
Make sure every source file includes SDL_config.h, so the proper system
headers are chosen.
