...e createCFGSimplificationPass was disabled on 2006/09/04. This causes some problems for architectures that use conditional moves to implement select (alpha and ARM). For example, on 2006/09/03 a "if (a) return 0; else return 1;" compiled to ---------------------------------------- zapnot $17,15,$1 zapnot $16,15,$2 bis $31,$31,$0 cmpeq $2,$1,$1 cmoveq $1,1,$0 ret $31,($26),1 ---------------------------------------- Now it compiles to ---------------------------------- zapnot $17,15,$0 zapnot $16,15,$1 cmpeq $1,$0,$0...

...o This is not because of how it handles select. For example: int %foo(int %x) { %b = seteq int %x, 5 %r = select bool %b, int 3, int 7 ret int %r } int %bar(int %x) { %b = seteq int %x, 5 br bool %b, label %t, label %f t: ret int 1 f: ret int 2 } compiles to: foo: lda $0,3($31) zapnot $16,15,$1 cmpeq $1,5,$1 cmoveq $1,7,$0 ret $31,($26),1 bar: zapnot $16,15,$0 cmpeq $0,5,$0 beq $0,$BB2_2 #f $BB2_1: #t lda $0,1($31) ret $31,($26),1 $BB2_2: #f lda $0,2($31) ret $31,($26),1 Which is not a problem wit...

Hi, Is the http://xenbits.xensource.com/linux-2.6-xen.hg tree still being updated? if not, what''s the preferred Linux tree to track that has all of the Xen bits?
