Hello,
last night I made some patches to the i386 asms to support
earlyclobbers. This is a menacing task. Any typo, forgetfulness or just
misunderstanding will definitely break the kernel.
BEWARE!
This patch (at last) compiles for me, though I get an early OOPS in idle
process (system halted). I just post it for having someone else take a
look at it and to start discussion whether it's the right way to go.
Interesting, the newer parts of the kernel (string-486.h) sometimes
already implemented earlyclobbers. Also there is a chance that I removed
some hidden bugs (I'm not always content with the argument passing.
Somewhere there might have been a "&" missing?).
If you fix it, please mail me directly - I'll take a closer look next
week.
Any comments welcome
Christof
PS: It has some pro and cons to apply a (perhaps working) patch for egcs
before 2.2.
+ egcs will definitely get popular (think of STL) and a lot of people
will use it for kernel compilation.
- This patch definitely destabilizes everything if it contains the
slightest error.
