> Hi all,
> Can gatekeeper help review fix for bug792:
> https://bugs.open64.net/show_bug.cgi?id=792
> All the changes are proposed to support the constraint "b" used in
> inline asm on IA-64:
>
> http://gcc.gnu.org/onlinedocs/gcc/Machine-Constraints.html#Machine-Constraints
> Intel IA-64―config/ia64/ia64.h
> b
> Branch register
>
> The changes in osprey/be/cg/localize.cxx is to fix a bug in
> localization phase. When the BB has asm or is the successor of asm BB,
> don't localize the dedicated TN since they are used and defined by
> asm.
> The changes in osprey/be/cg/ia64/cgtarget.cxx is to support the constraint
> "b".
> The changes in osprey/be/cg/ia64/exp_loadstore.cxx is to support
> load/store to/from branch register. Since the ld/st only support
> integer register, we need an extra copy between branch register and
> integer for the ld/st.
> The changes in osprey/be/cg/whirl2ops.cxx is to get the right register
> number from the dedicated branch register.
