[PowerPC] Temporarily disable VSX for PowerPC fast-isel tests Patch by Bill Seurer; some comment formatting changes by me. There are a few PowerPC test cases for FastISel support that currently fail with VSX support enabled. The temporary workaround under discussion in http://reviews.llvm.org/D5362 helps, but the tests still fail because they specify -fast-isel-abort, and the VSX workaround punts back to SelectionDAG. We have plans to fix FastISel permanently for VSX, but until that's in place these tests are preventing us from enabling VSX by default. Therefore we are adding -mattr=-vsx to these tests until the full support is ready. llvm-svn: 220172

; FIXME: FastISel currently returns false if it hits code that uses VSX
Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

; registers and with -fast-isel-abort=1 turned on the test case will then fail.

Use PIC relocation model as default for PowerPC64 ELF. Most of the PowerPC64 code generation for the ELF ABI is already PIC. There are four main exceptions: (1) Constant pointer arrays etc. should in writeable sections. (2) The TOC restoration NOP after a call is needed for all global symbols. While GNU ld has a workaround for questionable GCC self-calls, we trigger the checks for calls from COMDAT sections as they cross input sections and are therefore not considered self-calls. The current decision is questionable and suboptimal, but outside the scope of the change. (3) TLS access can not use the initial-exec model. (4) Jump tables should use relative addresses. Note that the current encoding doesn't work for the large code model, but it is more compact than the default for any non-trivial jump table. Improving this is again beyond the scope of this change. At least (1) and (3) are assumptions made in target-independent code and introducing additional hooks is a bit messy. Testing with clang shows that a -fPIC binary is 600KB smaller than the corresponding -fno-pic build. Separate testing from improved jump table encodings would explain only about 100KB or so. The rest is expected to be a result of more aggressive immediate forming for -fno-pic, where the -fPIC binary just uses TOC entries. This change brings the LLVM output in line with the GCC output, other PPC64 compilers like XLC on AIX are known to produce PIC by default as well. The relocation model can still be provided explicitly, i.e. when using MCJIT. One test case for case (1) is included, other test cases with relocation mode sensitive behavior are wired to static for now. They will be reviewed and adjusted separately.

[PowerPC] Add loads, stores, and related things to fast-isel. This is the next big chunk of fast-isel code. The primary purpose is to implement selection of loads and stores, but there is a lot of drag-along to support this. The common code to analyze addresses for both loads and stores is substantial. It's also necessary to add the materialization code for global values. Related to load-store processing is the code to fold loads into integer extends, since otherwise we generate lots of redundant instructions. We also need to add some overrides to some FastEmit routines to ensure we don't assign GPR 0 to a virtual register when this would change the meaning of an instruction. I added handling selection of a few binary arithmetic instructions, to enable committing some test cases I wrote a while back. Finally, ap couple of miscellaneous changes: * I cleaned up some poor style from a previous patch in PPCISelLowering.cpp, pointed out by David Blaikie. * I enlarged the Addr.Offset field to avoid sign problems with 32-bit offsets. llvm-svn: 189636
