5 years agoARM] Improve robustness of -mslow-flash-data
Thomas Preud'homme [Fri, 14 Dec 2018 19:20:29 +0000 (19:20 +0000)]
ARM] Improve robustness of -mslow-flash-data

Current code to handle -mslow-flash-data in machine description files
suffers from a number of issues which this patch fixes:

1) The insn_and_split in vfp.md to load a generic floating-point
constant via GPR first and move it to VFP register are guarded by
!reload_completed which is forbidden explicitely in the GCC internals
documentation section 17.2 point 3;

2) A number of testcase in the testsuite ICEs under -mslow-flash-data
when targeting the hardfloat ABI [1];

3) Instructions performing load from literal pool are not disabled.

These problems are addressed by 2 separate actions:

1) Making the splitters take a clobber and changing the expanders
accordingly to generate a mov with clobber in cases where a literal
pool would be used. The splitter can thus be enabled after reload since
it does not call gen_reg_rtx anymore;

2) Adding new predicates and constraints to disable literal pool loads
in existing instructions when -mslow-flash-data is in effect.

The patch also rework the splitter for DFmode slightly to generate an
intermediate DI load instead of 2 intermediate SI loads, thus relying on
the existing DI splitters instead of redoing their job. At last, the
patch adds some missing arm_fp_ok effective target to some of the
slow-flash-data testcases.

This new implementation has a smaller footprint than the previous

[libgomp, nvptx] Fix libgomp.c/target-5.c compilation

Libgomp test-case libgomp.c/target-5.c is failing to compile when building for
x86_64 with nvptx accelerator due to missing:
- getpid
- gethostname
- isatty (pulled in by fwrite)
in the nvptx newlib.

This patch fixes the build failure by:
- adding a function gomp_print_string which limits the use of fwrite to a single
  location (in affinity-fmt.c), and
- creating an nvptx version of affinity-fmt.c, which:
  - overrides the configure test results HAVE_GETPID and HAVE_GETHOSTNAME, and
  - implements fwrite using write.

Build and reg-tested on x86_64 with nvptx accelerator.

[AArch64][doc] Clarify -msve-vector-bits=128 behaviour

We've received reports about the -msve-vector-bits=128 bits being somewhat ambiguous.
It isn't clear whether -msve-vector-bits=128 forces vector-length-agnostic code or whether
-msve-vector-bits=scalable forces 128-bit vector-lengh-specific code.
The latter is a, perhaps unintuitive, reading that we want to exclude.

This patch makes it more explicit that -msve-vector-bits=128 is special and produces
vector-length *agnostic* code. In the end, I've rewritten the whole option documentation.

Checked make pdf that the output looks reasonable.

require profiling support for gcc.dg/lto/20100430-1_0.c test

This test currently fails unexpectedly if GCC is configured with
--disable-gcov, because it requires -fprofile-arcs. This patch
fixes the issue by requiring profiling support in order to run
this test.

Tested with two compilers, one built with --disable-gcov, resulting
in the test reporting an UNSUPPORTED result; and one built with gcov
support, resulting in 2 PASS tests.

gcc/testsuite/ChangeLog:

        * gcc.dg/lto/20100430-1_0.c: Add dg-require-profiling requirement.

5 years ago[libbacktrace] Add allocfail.sh test-case
Tom de Vries [Wed, 12 Dec 2018 13:50:51 +0000 (13:50 +0000)]
[libbacktrace] Add allocfail.sh test-case

Add test-case that forces alloc.c functions to fail, and check whether fail
handling is robust.

This is the test-case for "[libbacktrace] Fix segfault upon allocation
failure".  Without that patch, this test-case fails like this:
...
allocfail.sh: line 71: 26041 Segmentation fault      (core dumped) \
  ./allocfail $i > /dev/null 2>&1
Unallowed fail found: 13
FAIL allocfail.sh (exit status: 1)
...

This is a seperate patch because the test-case is nontrivial.

Bootstrapped and reg-tested on x86_64.

2018-12-12  Tom de Vries  <tdevries@suse.de>

* Makefile.am (TESTS): Add allocfail.sh.
