2014-05-14Fix ARM EHABI when function has landingpad and nounwind.Logan Chien2-8/+68
If the function has the landingpad instruction, then the handlerdata should be emitted even if the function has nouwnind attribute. Otherwise, following code will not work: void test1() noexcept { try { throw_exception(); } catch (...) { log_unexpected_exception(); } } Since the cantunwind was incorrectly emitted and the LSDA is not available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208791 91177308-0d34-0410-b5e6-96231b3b80d8

The commit r208166 will cause some regression on ARM EHABI. This fix has been committed in r208715, and an assertion failure test case has been committed in r208770. This commit further extends the unittest so that the actual value in the handlerdata will be checked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208790 91177308-0d34-0410-b5e6-96231b3b80d8

of that instruction try to eliminate the test. For example tzcntl %edi, %ebx testl %edi, %edi je .label can be rewritten into tzcntl %edi, %ebx jb .label A minor complication is that tzcnt sets CF instead of ZF when the input is zero, we have to rewrite users of the flags from ZF to CF. Currently we recognize patterns using lzcnt, tzcnt and popcnt.

2014-05-14[mips] Test that IAS for -mcpu=mips5 does not accept MIPS64 insns and ↵Daniel Sanders4-19/+97
-mcpu=mips(5|64) does not accept MIPS64r2 Summary: To limit the number of tests required, only one 64-bit ISA prior to MIPS64 are tested. rdhwr has been deliberately left without an ISA annotation for now. This is because the assembler and CodeGen disagree on when the instruction is available. Strictly speaking, it is only available in MIPS32r2 and MIPS64r2. However, it is emulated by a kernel trap on earlier ISA's and is necessary for TLS so CodeGen should emit it on older ISA's too.

2014-05-14ARM: implement support for the UDF mnemonicSaleem Abdulrasool11-41/+135
The UDF instruction is a reserved undefined instruction space. The assembler mnemonic was introduced with ARM ARM rev C.a. The instruction is not predicated and the immediate constant is ignored by the CPU. Add support for the three encodings for this instruction. The changes to the invalid instruction test is due to the fact that the invalid instructions actually overlap with the undefined instruction. Introduction of the new instruction results in a partial decode as an undefined sequence. Drop the tests as they are invalid instruction patterns anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208751 91177308-0d34-0410-b5e6-96231b3b80d8

2014-05-14Recommit r208506: DebugInfo: Include lexical scopes in inlined subroutines.David Blaikie5-21/+173
This was reverted in r208642 due to regressions surrounding file changes within lexical scopes causing inlining information to be lost. The issue was in LexicalScopes::getOrCreateInlinedScope, where I was previously testing "isLexicalBlock" which is false for "DILexicalBlockFile" (a scope used to represent changes in the current file name) and assuming it was then a function (breaking out of the inlined scope path and reaching for the parent non-inlined scopes). By inverting the condition and testing for "isSubprogram" the correct behavior is attained. (also found some weirdness in Clang, see r208742 when reducing this test case - the resulting test case doesn't apply with the Clang fix, but I've added a more realistic test case to inline-scopes.ll which does reproduce the issue and demonstrate the fix) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208748 91177308-0d34-0410-b5e6-96231b3b80d8

To limit the number of tests required, only one 32-bit and one 64-bit ISA prior to MIPS32/MIPS64 are tested. rdhwr has been deliberately left without an ISA annotation for now. This is because the assembler and CodeGen disagree on when the instruction is available. Strictly speaking, it is only available in MIPS32r2 and MIPS64r2. However, it is emulated by a kernel trap on earlier ISA's and is necessary for TLS so CodeGen should emit it on older ISA's too.
