TODO:
- Un-bitrot ISel
- Hook up If-Conversion a la ARM target
- Hook up all branch analysis functions
- Instruction scheduling
- Bundling
- Dynamic Optimization
- Testing and bugfixing
- stop passing FP args in both FP *and* integer regs when not required
- allocate low (nonstacked) registers more aggressively
- clean up and thoroughly test the isel patterns.
- fix stacked register allocation order: (for readability) we don't want
the out? registers being the first ones used
- fix up floating point
(nb http://gcc.gnu.org/wiki?pagename=ia64%20floating%20point )
- bundling!
(we will avoid the mess that is:
http://gcc.gnu.org/ml/gcc/2003-12/msg00832.html )
- instruction scheduling (hmmmm! ;)
- counted loop support
- make integer + FP mul/div more clever (we have fixed pseudocode atm)
- track and use comparison complements
INFO:
- we are strictly LP64 here, no support for ILP32 on HP-UX. Linux users
don't need to worry about this.
- i have instruction scheduling/bundling pseudocode, that really works
(has been tested, albeit at the perl-script level).
so, before you go write your own, send me an email!
KNOWN DEFECTS AT THE CURRENT TIME:
- C++ vtables contain naked function pointers, not function descriptors,
which is bad. see http://llvm.cs.uiuc.edu/bugs/show_bug.cgi?id=406
- varargs are broken
- alloca doesn't work (indeed, stack frame layout is bogus)
- no support for big-endian environments
- (not really the backend, but...) the CFE has some issues on IA64.
these will probably be fixed soon.
