2005-11-06just some random hacking - calls (particularly indirect) need a lot ofDuraid Madina
love (especially with -sched=simple) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24225 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-06ask for 16-byte aligned jmpbufs. This should unbreak C++ on IA64 (andDuraid Madina
a bunch of other things) but is currently ignored by the code generator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24206 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-04oops, forgot to load GP for indirect calls, though the old code now commentedDuraid Madina
out failed (e.g. methcall) - now the code compiles, though it's not quite right just yet (tm) ;) would fix this but it's 3am! :O git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24186 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-02"fix" support for FP constants (this code asserts in the scheduler,Duraid Madina
though) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24152 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-02add support for SELECT to TargetSelectionDAG.td, add support forDuraid Madina
selecting ints to IA64, and a few other ia64 bits and pieces git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24147 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-02add support for loading FP constants +0.0 and +1.0 to the dag isel,Duraid Madina
stop pretending -0.0 and -1.0 are machine constants git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24146 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-01FORTRAN!!! :( and other similarly unfortunate things mean that on ia64Duraid Madina
one sometimes needs to pass FP args in both FP *and* integer registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24134 91177308-0d34-0410-b5e6-96231b3b80d8

clever little tablegen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24133 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-29add some FP stuff, some mix.* stuff, and constant pool support to theDuraid Madina
DAG instruction selector, which should be destroyed one day (in the pattern isel also) since ia64 can pack any constant in the instruction stream git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24094 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-28DAG->DAG instruction selection for ia64! "hello world" works, not much else.Duraid Madina
use -enable-ia64-dag-isel to turn this on TODO: delete lowering stuff from the pattern isel : get operations on predicate bits working : get other bits of pseudocode going : use sampo's mulh/mull-using divide-by-constant magic : *so* many patterns ("extr", "tbit" and "dep" will be fun :) : add FP : add a JIT! : get it working 100% in short: this'll be happier in a couple of weeks, but it's here now so the tester can make me feel guilty sooner. OTHER: there are a couple of fixes to the pattern isel, in particular making the linker happy with big blobs of fun like pypy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24058 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-30these registers don't belong to any register classes, so don't mark themChris Lattner
as callee save. They can never be generated by the compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23551 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-28Add FP versions of the binary operators, keeping the int and fp worlds seperate.Chris Lattner
Though I have done extensive testing, it is possible that this will break things in configs I can't test. Please let me know if this causes a problem and I'll fix it ASAP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23505 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26Change ConstantPoolSDNode to actually hold the Constant itself instead ofChris Lattner
putting it into the constant pool. This allows the isel machinery to create constants that it will end up deciding are not needed, without them ending up in the resultant function constant pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23081 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-19a bugfix (up top) and a quick repair job: disable generation of dep.zDuraid Madina
(which died about a week ago) so we're back to load-(2^n-1)-then-AND sequences. slow, but things should now be Almost Completely Working, modulo those pesky alignment/ABI issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22904 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-19Mark some instructions as variable_ops, and PSEUDO_ALLOC as taking a GPR.Chris Lattner
I'm not convinced this is all of them, but I can't do much testing, because IA64 LLC crashes on big programs :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22892 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-10sorry!! this is temporary; for some reason the nasty constmul code seems toDuraid Madina
be an infinite loop when using g++-4.0.1*, this kills the ia64 nightly tester. A proper fix shall be forthcoming!!! thanks for not killing me. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22748 91177308-0d34-0410-b5e6-96231b3b80d8
