* Print a=b as an assignment.Rafael Espindola2014-06-24
| | | | | | | | | | | In assembly the expression a=b is parsed as an assignment, so it should be printed as one. This remove a truly horrible hack for producing a label with "a=.". It would be used by codegen but would never be reached by the asm parser. Sorry I missed this when it was first committed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211639 91177308-0d34-0410-b5e6-96231b3b80d8

* Add load/store functionalityReed Kotler2014-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patches allows non conversions like i1=i2; where both are global ints. In addition, arithmetic and other things start to work since fast-isel will use existing patterns for non fast-isel from tablegen files where applicable. In addition i8, i16 will work in this limited context for assignment without the need for sign extension (zero or signed). It does not matter how i8 or i16 are loaded (zero or sign extended) since only the 8 or 16 relevant bits are used and clang will ask for sign extension before using them in arithmetic. This is all made more complete in forthcoming patches. for example: int i, j=1, k=3; void foo() { i = j + k; } Keep in mind that this pass is not enabled right now and is an experimental pass It can only be enabled with a hidden option to llvm of -mips-fast-isel. Test Plan: Run test-suite, loadstore2.ll and I will run some executable tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the behaviour of the function. MipsDelaySlotFiller now invalidates the liveness information when moving instructions to the delay slot. Without this, divrem.ll will abort since %GP ends up used before it is defined.

* SelectionDAG: Don't use MVT::Other to determine legality of ISD::SELECT_CCTom Stellard2014-06-10
| | | | | | | | | | | | | The SelectionDAG bad a special case for ISD::SELECT_CC, where it would allow targets to specify: setOperationAction(ISD::SELECT_CC, MVT::Other, Expand); to indicate that they wanted to expand ISD::SELECT_CC for all types. This wasn't applied correctly everywhere, and it makes writing new DAG patterns with ISD::SELECT_CC difficult. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210541 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | I saw at least a memory leak or two from inspection (on probably untested error paths) and r206991, which was the original inspiration for this change. I ran this idea by Jim Grosbach a few weeks ago & he was OK with it. Since it's a basically mechanical patch that seemed sufficient - usual post-commit review, revert, etc, as needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210427 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert "Do materialize for floating point"Alp Toker2014-06-08
| | | | | | | | | | | | | | | | | | | | | | | 1) The commit was made despite profound lack of understanding: "I did not understand the comment about using dyn_cast instead of isa. I will commit as is and make the update after. You can explain what you meant to me." Commit first, understand later isn't OK. 2) Review comments were simply ignored: "Can you edit the summary to describe what the patch is for? It appears to be a list of commits at the moment." 3) The patch got LGTM'd off-list without any indication of readiness. 4) The public mailing list was excluded from patch review so all of this was hidden from the community. This reverts commit r210414. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210424 91177308-0d34-0410-b5e6-96231b3b80d8
