2011-08-30Do not try to rematerialize a value from a partial definition.Bob Wilson
I don't currently have a good testcase for this; will try to get one tomorrow. <rdar://problem/10032939> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138794 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-30Change ARM / Thumb2 addc / adde and subc / sube modeling to use physicalEvan Cheng
register dependency (rather than glue them together). This is general goodness as it gives scheduler more freedom. However it is motivated by a nasty bug in isel. When a i64 sub is expanded to subc + sube. libcall #1 \ \ subc \ / \ \ / \ \ / libcall #2 sube If the libcalls are not serialized (i.e. both have chains which are dag entry), legalizer can serialize them in arbitrary orders. If it's unlucky, it can force libcall #2 before libcall #1 in the above case. subc | libcall #2 | libcall #1 | sube However since subc and sube are "glued" together, this ends up being a cycle when the scheduler combine subc and sube as a single scheduling unit. The right solution is to fix LegalizeType too chains the libcalls together. However, LegalizeType is not processing nodes in order so that's harder than it should be. For now, the move to physical register dependency will do. rdar://10019576 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138791 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-29Explicitly zero out parts of a vector which are required to be zero by the ↵Eli Friedman
algorithm in LowerUINT_TO_FP_i32. This only has a substantial effect on the generated code when the input is extracted from a vector register; other ways of loading an i32 do the appropriate zeroing implicitly. Fixes PR10802. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138768 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-29addrmode_imm12 and addrmode2_offset encode their immediate values ↵Owen Anderson
differently. Update the manual instruction selection code that was encoding them the addrmode2 way even though LDR_PRE_IMM/LDRB_PRE_IMM had switched to addrmode_imm12.

This handles only the handling of the IT instruction itself, not the processing and validation of the instructions in the IT block. That's next, and will include encoding tests for IT itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138665 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-26invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We ↵Owen Anderson
were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138653 91177308-0d34-0410-b5e6-96231b3b80d8
