6 years ago[ARM][PR target/84826] Fix ICE in extract_insn, at recog.c:2304 on
Sudakshina Das [Thu, 22 Mar 2018 17:24:41 +0000 (17:24 +0000)]
[ARM][PR target/84826] Fix ICE in extract_insn, at recog.c:2304 on
arm-linux-gnueabi

The ICE in the bug report was happening because the macro
USE_RETURN_INSN (FALSE) was returning different values at different points
in the compilation. This was internally occurring because the function
arm_compute_static_chain_stack_bytes () which was dependent on
arm_r3_live_at_start_p () was giving a different value after the cond_exec
instructions were created in ce3 causing the liveness of r3 to escape up
to the start block.

The function arm_compute_static_chain_stack_bytes () should really only
compute the value once duringepilogue/prologue stage. This pass introduces
a new member 'static_chain_stack_bytes' to the target definition of the
struct machine_function which gets calculated in expand_prologue and is the
value that is returned by arm_compute_static_chain_stack_bytes () beyond that.

6 years agoAdjust __builtin_tgmath handling of integer arguments to _FloatN narrowing macros.
Joseph Myers [Wed, 21 Mar 2018 22:29:37 +0000 (22:29 +0000)]
Adjust __builtin_tgmath handling of integer arguments to _FloatN narrowing macros.

When adding __builtin_tgmath to support a better tgmath.h
implementation, I noted that further changes might be needed regarding
the TS 18661 functions that round their results to a narrower type,
because of unresolved issues with how the corresponding type-generic
macros are defined in TS 18661.

The resolution of those issues is still in flux, but the latest
version does indeed require something slightly different from
__builtin_tgmath.  It specifies that integer arguments to type-generic
macros such as f32xadd are treated as _Float64 not double - which was
also present in earlier versions of the resolution - but then it also
specifies different handling for _Float64 arguments and double
arguments, which wasn't in earlier versions.  Specifically, in the
latest version
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2213.pdf>, f32xadd
with _Float64 arguments would call f32xaddf64, while f32xadd with
double arguments would call f32xaddf64x.  Since integer arguments are
converted directly to the argument type of the selected function (not
to double / _Float64x unless that ends up as the argument type), this
is a user-visible difference in semantics that means __builtin_tgmath
actually needs to implement treating integer arguments as _Float64 in
this case (the rest of the latest semantics can then be implemented in
the header, with a few inline functions there).

To avoid releasing with the older version of the __builtin_tgmath
semantics that doesn't work with the latest proposed DR#13 resolution,
this patch implements a rule in __builtin_tgmath that maps integer
types to _Float64 (respectively _Complex _Float64 for complex integer
types) where all the specified functions return the same _FloatN or
_FloatNx type.  This does not affect any existing uses of
__builtin_tgmath in glibc's or GCC's tgmath.h since I haven't yet
added any of these type-generic macros to glibc when adding the
corresponding narrowing functions.

[PR c++/84610,84642] recover from implicit template parms gracefully

If we get a parse error during an attempted fully implicit function
template parse, and need to skip to the end of the statement or block,
we may discard the function parms scope rather than the enclosing
injected implicit template parms scope.  If we rollback a tentative
parse and try something else, we'll no longer be in a function parms
scope, but rather in a template parms scope, but we may still attempt
to synthesize implicit template parms and then fail the assert that
checks we're in a function parms scope.

This patch introduces an alternative to
finish_fully_implicit_template_p, to be used during error recovery,
that floats the implicit template parm scope to the top so that it
gets discarded as we finish and discard the failed implicit template
data, while other scopes are retained as expected.  It also clears the
implicit template parser data as we finish the template, so that it
doesn't linger on referencing discarded or used scopes and parms.

[ARM] Fix test pr82989.c for big endian and mthumb

The test pr82989.c which was added in one of previous commits is failing for
mthumb and big-endian configurations. The aim of this test was to check that
NEON instructions are not being used for simple shift operations. The scanning
of lsl and lsr instructions and checking its counts were just too restrictive
for different configurations. So I have now simplified the test to only check
for the absence of NEON instructions.

6 years agoThis PR shows that we get the load/store_lanes logic wrong for arm big-endian.
Kyrylo Tkachov [Tue, 20 Mar 2018 17:13:16 +0000 (17:13 +0000)]
This PR shows that we get the load/store_lanes logic wrong for arm big-endian.

It is tricky to get right. Aarch64 does it by adding the appropriate lane-swapping
operations during expansion.

I'd like to do the same on arm eventually, but we'd need to port and validate the VTBL-generating
code and add it to all the right places and I'm not comfortable enough doing it for GCC 8, but I am keen
in getting the wrong-code fixed.
As I say in the PR, vectorisation on armeb is already severely restricted (we disable many patterns on BYTES_BIG_ENDIAN)
and the load/store_lanes patterns really were not working properly at all, so disabling them is not
a radical approach.

The way to do that is to return false in ARRAY_MODE_SUPPORTED_P for BYTES_BIG_ENDIAN.

Bootstrapped and tested on arm-none-linux-gnueabihf.
Also tested on armeb-none-eabi.

     PR target/82518
     * config/arm/arm.c (arm_array_mode_supported_p): Return false for
     BYTES_BIG_ENDIAN.

     * lib/target-supports.exp (check_effective_target_vect_load_lanes):
     Disable for armeb targets.

[PR81647][AARCH64] Fix handling of Unordered Comparisons in aarch64-simd.md

This patch fixes the inconsistent behavior observed at -O3 for the unordered
comparisons. According to the online docs (https://gcc.gnu.org/onlinedocs
/gcc-7.2.0/gccint/Unary-and-Binary-Expressions.html), all of the following
should not raise an FP exception:
- UNGE_EXPR
- UNGT_EXPR
- UNLE_EXPR
- UNLT_EXPR
- UNEQ_EXPR
Also ORDERED_EXPR and UNORDERED_EXPR should only return zero or one.

The aarch64-simd.md handling of these were generating exception raising
instructions such as fcmgt. This patch changes the instructions that are
emitted in order to not give out the exceptions. We first check each
operand for NaNs and force any elements containing NaN to zero before using
them in the compare.

Example: UN<cc> (a, b) -> UNORDERED (a, b)
  | (cm<cc> (isnan (a) ? 0.0 : a, isnan (b) ? 0.0 : b))

The ORDERED_EXPR is now handled as (cmeq (a, a) & cmeq (b, b)) and
UNORDERED_EXPR as ~ORDERED_EXPR and UNEQ as (~ORDERED_EXPR | cmeq (a,b)).
