[PowerPC] Refactor soft-float support, and enable PPC64 soft float

This change enables soft-float for PowerPC64, and also makes soft-float disable
all vector instruction sets for both 32-bit and 64-bit modes. This latter part
is necessary because the PPC backend canonicalizes many Altivec vector types to
floating-point types, and so soft-float breaks scalarization support for many
operations. Both for embedded targets and for operating-system kernels desiring
soft-float support, it seems reasonable that disabling hardware floating-point
also disables vector instructions (embedded targets without hardware floating
point support are unlikely to have Altivec, etc. and operating system kernels
desiring not to use floating-point registers to lower syscall cost are unlikely
to want to use vector registers either). If someone needs this to work, we'll
need to change the fact that we promote many Altivec operations to act on
v4f32. To make it possible to disable Altivec when soft-float is enabled,
hardware floating-point support needs to be expressed as a positive feature,
like the others, and not a negative feature, because target features cannot
have dependencies on the disabling of some other feature. So +soft-float has

7 years agoUse __builtin_isnan/isinf/isfinite in complex
Hal Finkel [Sat, 1 Oct 2016 20:38:31 +0000 (20:38 +0000)]
Use __builtin_isnan/isinf/isfinite in complex

The libc-provided isnan/isinf/isfinite macro implementations are specifically
designed to function correctly, even in the presence of -ffast-math (or, more
specifically, -ffinite-math-only). As such, on most implementation, these
either always turn into external function calls (e.g. glibc) or are
specifically function calls when FINITE_MATH_ONLY is defined (e.g. Darwin).

Our implementation of complex arithmetic makes heavy use of isnan/isinf/isfinite
to deal with corner cases involving non-finite quantities. This was problematic
in two respects:

  1. On systems where these are always function calls (e.g. Linux/glibc), there was a
     performance penalty
  2. When compiling with -ffast-math, there was a significant performance
     penalty (in fact, on Darwin and systems with similar implementations, the code
     may in fact be slower than not using -ffast-math, because the inline
     definitions provided by libc become unavailable to prevent the checks from
     being optimized out).

Eliding these inf/nan checks in -ffast-math mode is consistent with what
happens with libstdc++, and in my experience, what users expect. This is
critical to getting high-performance code when using complex<T>. This change
replaces uses of those functions on basic floating-point types with calls to
__builtin_isnan/isinf/isfinite, which Clang will always expand inline. When
using -ffast-math (or -ffinite-math-only), the optimizer will remove the checks
as expected.

'lit.py' and 'lit', in order to increase uniformity between all LLVM
projects and support using installed lit.

Changing the conditional used to determine whether in-tree or external
lit is being used covers the case when LLVM_MAIN_SRC_DIR is defined but
does not exist (anymore). In this case, the functions falls back to
looking for installed lit rather than attempting to use a non-existing
path. The same conditional is used in clang already.

Making LIT_COMMAND a cache variable in case the source tree variant is
used serves two purposes. Firstly, it increases uniformity between
the two branches since find_program() implicitly makes LIT_COMMAND
a cache variable. Secondly, it allows overriding the lit executable used
to run the tests when the LLVM source tree is provided. Gentoo is
planning to use this to use installed (and byte-compiled) lit instead of
re-compiling it in every LLVM project.

Extending default search is meant to increase uniformity between
different LLVM projects. The 'lit.py' name is already used by a few of
them, and 'lit' is the name used by utils/lit/setup.py when installing.

test infra: clear file-charged issues on rerun of file

This change addresses the corner case bug in the test
infrastructure where a test file times out *outside*
of any running test method.  In those cases, the issue
was charged to the file, not to a test method within
the file.  When that file is re-run successfully,
none of the test-method-level successes would clear
the file-level issue.

This change fixes that: for all test files that are
getting rerun (whether by being marked flaky or
via the --rerun-all-issues flag), file-level test
issues are searched for in each of those files.  Each
file-level issue found in the rerun file list then
gets cleared.

A test of this feature is added to issue_verification,
using the technique there of moving the *.py.park file
to *.py to do an end-to-end validation.

formatting violations in files I touched.
