2010-03-04Teach lit to honor conditional directives. The syntax is:John McCall
IF(condition(value)): If the value satisfies the condition, the line is processed by lit; otherwise it is skipped. A test with no unignored directives is resolved as Unsupported. The test suite is responsible for defining conditions; conditions are unary functions over strings. I've defined two conditions in the LLVM test suite, TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values like those in llvm_bindings). So for example you can write: IF(BINDING(ocaml)): RUN: %blah %s -o - and the RUN line will only execute if LLVM was configured with the ocaml bindings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97726 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-16Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin
The large code model is documented at http://www.x86-64.org/documentation/abi.pdf and says that calls should assume their target doesn't live within the 32-bit pc-relative offset that fits in the call instruction. To do this, we turn off the global-address->target-global-address conversion in X86TargetLowering::LowerCall(). The first attempt at this broke the lazy JIT because it can separate the movabs(imm->reg) from the actual call instruction. The lazy JIT receives the address of the movabs as a relocation and needs to record the return address from the call; and then when that call happens, it needs to patch the movabs with the newly-compiled target. We could thread the call instruction into the relocation and record the movabs<->call mapping explicitly, but that seems to require at least as much new complication in the code generator as this change. To fix this, we make lazy functions _always_ go through a call stub. You'd think we'd only have to force lazy calls through a stub on difficult platforms, but that turns out to break indirect calls through a function pointer. The right fix for that is to distinguish between calls and address-of operations on uncompiled functions, but that's complex enough to leave for someone else to do. Another attempt at this defined a new CALL64i pseudo-instruction, which expanded to a 2-instruction sequence in the assembly output and was special-cased in the X86CodeEmitter's emitInstruction() function. That broke indirect calls in the same way as above. This patch also removes a hack forcing Darwin to the small code model. Without far-call-stubs, the small code model requires things of the JITMemoryManager that the DefaultJITMemoryManager can't provide. Thanks to echristo for lots of testing! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88984 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18Support GoogleTest's "typed tests"Jeffrey Yasskin
(http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Typed_Tests) in lit.py. These tests have names like "ValueMapTest/0.Iteration", which broke when lit.py os.path.join()ed them onto the path and then assumed it could os.path.split() them back off.
