I have a file that will not compile with hc2.1s. It appears to be
related to register maps for leaf functions, as it goes away if I
delete the body of a static function called from the one that causes
the error. If you "cd /afs/athena/user/j/jfc/build/hcbug ; make
path.o" you will get this error:
[color]These are the allocable machine registers in bank 1 & their masks, in allocation order:
r0=[R1..R14 ] r2=[R1..R14 ] r3=[R1..R14 ] r4=[R1..R14 ] r5=[R1..R14 ] r15=[R1..R14 ] r14=[R1..R14 ] r13=[R1..R14 ] r12=[R1..R14 ] r11=[R1..R14 ] r10=[R1..R14 ] r9=[R1..R14 ] r8=[R1..R14 ] r7=[R1..R14 ] r6=[R1..R14 ] sp=[R1..R14 ]
[color]Can't map register R32[mask=8e][size=4]!
Adjacencies for register R32:

Can't map to register r0 because r0 is in rtab[R32].vec
-- For the same reason, I can't map to machine register(s) r2 r3 r4 r5 r15 r14 r13 r12 r11 r10 r9 r8 r7 r6 sp
