Syllable

[NecroRomancist]

I thought i'd create a list of software we have or will have to re-test / recompile once we have mmap /mprotect.

dosbox - can use mprotect for its recompiling engine. Otherwise it will fallback to malloc which is why the recompiling engine is slower under Syllable.
SDL - uses mprotect for software scaling.
JamVM - uses mmap in a similar way to dosbox.
PostgreSQL - requires mmap.
GTK+ (indirect renderer - Cairo - ) - looks for a working mmap @ configure.
cherokee - requires mmap
gnash >= 0.8.3 - makes use of shm and mmap.Can't be compiled otherwise..

These are the ones i know of..

GCC 4.2+ requires mmap()

Checked in a first-pass implementation of mmap() & munmap(). mprotect() is currently a stub but will be simple to implement.

I'm building GCC 4.2.3 right now to test, although some software already uses mmap() if it's available: Freetype for example (this was a surprise to me) and the system is booting, so it's working.

As a nice extra file-backed MAP_SHARED mmap() was easy to support, so we should have full mmap() support in 0.6.7.

mmap(), mprotect(), msync() & munmap() are now in CVS.
