Subject: [9fans] JIT (mostly off topic)
Date: Tue, 9 Sep 2014 22:45:01 +0100 [thread overview]
Message-ID: <5027045b88fe7d178a0926131e4205f1@quintile.net> (raw)
Years ago The Commander and Bart Locanthi used JIT
in the form of some C that write machine code into an
array of chars, cast it to a function pointer, and called it.
(I appologise if the details are not correct but this is the idea).
I have a need for such a thing again - trying to speed up
a compressed video decoder.
Anyone done such a thing this millenium? Does the x86 data execution
prevention mean you just cannot do this - my targets are desktop OSs
other than plan9 (sadly).
-Steve
