Sudakshina Das [Thu, 14 Dec 2017 10:35:38 +0000 (10:35 +0000)]
[PATCH PR81228][AARCH64]Fix ICE by adding LTGT in vec_cmp<mode><v_int_equiv>

This patch is a follow up to the existing discussions on
https://gcc.gnu.org/ml/gcc-patches/2017-07/msg01904.html
Bin had earlier submitted this patch to fix the ICE that
occurs because of the missing LTGT in aarch64-simd.md.
That discussion opened up a new bug report PR81647 for
an inconsistent behavior.

As discussed earlier on the gcc-patches discussion and on
the bug report, PR81647 was occurring because of how UNEQ
was handled in aarch64-simd.md rather than LTGT.
Since __builtin_islessgreater is guaranteed to not give an
FP exception but LTGT might, __builtin_islessgreater gets
converted to ~UNEQ very early on in fold_builtin_unordered_cmp.
Thus I will post a separate patch for correcting how UNEQ and
other unordered comparisons are handled in aarch64-simd.md.

This patch is only adding the missing LTGT to plug the ICE.

Testing done: Checked for regressions on bootstrapped
aarch64-none-linux-gnu and added a new compile time test case
that gives out LTGT to make sure it doesn't ICE

6 years agopoly_int: add poly-int.h
Richard Sandiford [Thu, 14 Dec 2017 00:06:02 +0000 (00:06 +0000)]
poly_int: add poly-int.h

This patch adds a new "poly_int" class to represent polynomial integers
of the form:

  C0 + C1*X1 + C2*X2 ... + Cn*Xn

It also adds poly_int-based typedefs for offsets and sizes of various
precisions.  In these typedefs, the Ci coefficients are compile-time
constants and the Xi indeterminates are run-time invariants.  The number
of coefficients is controlled by the target and is initially 1 for all
ports.

Most routines can handle general coefficient counts, but for now a few
are specific to one or two coefficients.  Support for other coefficient
counts can be added when needed.

The patch also adds a new macro, IN_TARGET_CODE, that can be
set to indicate that a TU contains target-specific rather than
target-independent code.  When this macro is set and the number of
coefficients is 1, the poly-int.h classes define a conversion operator
to a constant.  This allows most existing target code to work without
modification.  The main exceptions are:

- values passed through ..., which need an explicit conversion to a
  constant

- ?: expression in which one arm ends up being a polynomial and the
  other remains a constant.  In these cases it would be valid to convert
  the constant to a polynomial and the polynomial to a constant, so a
  cast is needed to break the ambiguity.

The patch also adds a new target hook to return the estimated
value of a polynomial for costing purposes.

The patch also adds operator<< on wide_ints (it was already defined
for offset_int and widest_int).  I think this was originally excluded
because >> is ambiguous for wide_int, but << is useful for converting
bytes to bits, etc., so is worth defining on its own.  The patch also
adds operator% and operator/ for offset_int and widest_int, since those
types are always signed.  These changes allow the poly_int interface to
be more predictable.

I'd originally tried adding the tests as selftests, but that ended up
bloating cc1 by at least a third.  It also took a while to build them
at -O2.  The patch therefore uses plugin tests instead, where we can
force the tests to be built at -O0.  They still run in negligible time
when built that way.

6 years agoExpensive selftests: torture testing for fix-it boundary conditions (PR c/82050)

Expensive selftests: torture testing for fix-it boundary conditions (PR c/82050)

This patch adds selftest coverage for the fix for PR c/82050.

The selftest iterates over various "interesting" column and line-width
values to try to shake out bugs in the fix-it printing routines, a kind
of "torture" selftest.

Unfortunately this selftest is noticably slower than the other selftests;
adding it to diagnostic-show-locus.c led to:
  -fself-test: 40218 pass(es) in 0.172000 seconds
slowing down to:
  -fself-test: 97315 pass(es) in 6.109000 seconds
for an unoptimized build (e.g. when hacking with --disable-bootstrap).

Given that this affects the compile-edit-test cycle of the "gcc"
subdirectory, this felt like an unacceptable amount of overhead to add.

I attempted to optimize the test by reducing the amount of coverage, but
the test seems useful, and there seems to be a valid role for "torture"
selftests.

Hence this patch adds a:
  gcc.dg/plugin/expensive_selftests_plugin.c
with the responsibility for running "expensive" selftests, and adds the
expensive test there.  The patch moves a small amount of code from
selftest::run_tests into a helper class so that the plugin can print
a useful summary line (to reassure us that the tests are actually being
run).

With that, the compile-edit-test cycle of the "gcc" subdir is unaffected;
the plugin takes:
  expensive_selftests_plugin: 26641 pass(es) in 3.127000 seconds
which seems reasonable within the much longer time taken by "make check"
(I optimized some of the overhead away, hence the reduction from 6 seconds
above down to 3 seconds).

[arm] PR target/83206: Make native driver select fp-capable armv6 cores

A quirk in the historical naming of some ARMv6 products means that the
main CPU name implies the presence or otherwise of the floating point unit.
This causes problems when using -mfpu=auto with -mcpu=native: the driver is
picking a CPU that does not support a floating-point unit, even though
one may well exist.

This patch addresses this by selecting the FP-capable names so that FP
instructions will be generated if the other options suggest this is
permitted.

Note that a more complete fix is really needed here to look up the
FP/simd capabilities and append the appropriate capability extensions.
This will be the subject of some follow-up patches.

6 years ago[arm] Don't strip off all architecture features from -march passed to assembler
Richard Earnshaw [Fri, 8 Dec 2017 11:14:09 +0000 (11:14 +0000)]
[arm] Don't strip off all architecture features from -march passed to assembler

When GCC invokes the assembler it generates a sanitized version of the
user-specified -march option to pass through, since the assembler does
not understand all the new FPU-related architectural options.
Unfortunately it goes too far and strips off all the architectural
extensions, including some that are unrelated to the -mfpu variant
selected.

Again, this doesn't really matter when compiling C code because the
compiler will override the command-line specified architecture with
directives in the assembly file itself, but when using the compiler
driver to invoke the assembler the only indiciation of the desired
architecture might come from the command line.

We fix this by adjusting the canonicalization pass to remove any
option that only specifies features that can be expressed by -mfpu
(any that go beyond that are already supported by the assembler).  We
do have to take care to re-order the options, though as the assembler
expects feature options to be in a canonical order (unlike the
compiler, where ordering is handled left-to-right: there's only a
difference if there are negation options, but a canonicalized
architecture string shouldn't have any of those).  We do this by
recording which options we need and then sorting the final list
alphabetically.

* common/config/arm/arm-common.c: Include <algorithm>.
(INCLUDE_VECTOR): Define.
(compare_opt_names): New function.
(arm_rewrite_selected_arch): Only strip out extensions that can be
expressed through -mfpu.  Sort the remaining extensions
alphabetically.

6 years ago[arm] Generate a -mfpu= option for passing to the assembler
Richard Earnshaw [Fri, 8 Dec 2017 10:55:01 +0000 (10:55 +0000)]
[arm] Generate a -mfpu= option for passing to the assembler

When gcc runs with the new -mfpu=auto option (either explicitly or
when that's the default behaviour) then this option is not passed
through to the assembler as we cannot rely on the assembler
understanding it (currently it doesn't understand it at all, but in
future that might change).  That means that the assembler falls back
to its builtin default, which may not correspond to what the user
expected based on the command-line options they passed.

Normally that wouldn't matter because assembler files generated by the
compiler will contain explicit directives that set the FPU type
directly and override any internal defaults; but when the compiler
driver is used to invoke the assembler directly (because the source
file ends in .s or .S) then this might cause a problem if that assumes
the FPU matches the compiler.

To address this, this patch makes the driver construct a -mfpu= option
for the assembler in the same way as the compiler generates an
internal .fpu directive.  As mentioned, this makes no difference if
the assembler file explicitly overrides the command line options, but
helps in the case where this is implicit.
