-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.
