[PATCH 1/3] valgrind: let valgrind determine its own optimisation flags

From: Andre McCurdy <hidden>
Date: 2016-01-20 01:34:13

Valgrind likes to control its own optimisation flags. It generally
defaults to -O2 but uses -O0 for some specific test apps etc. Passing
our own flags (via CFLAGS) means we interfere with that.

Giving valgrind control of optimisation is hopefully an even better
solution than the previous one of forcing -O0 for all tests.

[PATCH 2/3] valgrind: re-enable ARM intdiv and vcvt_fixed_float_VFP tests

From: Andre McCurdy <hidden>
Date: 2016-01-20 01:34:15

The intdiv test has been fixed upstream and the vcvt_fixed_float_VFP
test can be fixed with a similar approach, ie ensuring that it is
always compiled with appropriate -mcpu/-mfpu flags to support the
instructions being tested.

See similar cases in none/tests/arm/Makefile.am

[PATCH 3/3] valgrind: avoid neon for targets which don't support it

From: Andre McCurdy <hidden>
Date: 2016-01-20 01:34:17

The sh-mem-random.c test app tries to use neon loads and stores to
test 64-bit float copies when building for ARM. Allow it to do so if
possible, but fallback to C when building for ARM targets which don't
support neon.

The intdiv test has been fixed upstream and the vcvt_fixed_float_VFP
test can be fixed with a similar approach, ie ensuring that it is
always compiled with appropriate -mcpu/-mfpu flags to support the
instructions being tested.

See similar cases in none/tests/arm/Makefile.am

-Remove arm tests that don't compile

-Upstream-Status: Pending

-Corrects the original commit for the patch that removed ARM ptest CFLAGS
-settings. Since the flags could be set by a user, the flags should
-be kept in place during compilation.  By keeping the original up-stream
-CFLAGS for the tests, then additional tests successfully compile
-for all tested ARM tunings.
-
-However, there were still two tests listed below that did not compile
-for any beaglebone tuning that is valid for valgrind. With the updated
-patch, the set of excluded ARM ptests and their respective build
-failures are:
-  intdiv - fails for all beaglebone tunings with 2 errors:
-  {standard input}:(40 or 41): Error: selected processor does not
-       support Thumb mode `udiv r3,r9,r10'
-  {standard input}:(72 or 73): Error: selected processor does not
-       support Thumb mode `sdiv r3,r9,r10'
-
-  vcvt_fixed_float_VFP - fails for all beaglebone tunings in one of
-  two ways:
-    with neon tuning (-mfpu=neon) fails with Internal Compiler Error
-    without neon tuning fails with 3 errors:
-    {standard input}:33: Error: selected FPU does not support
-      instruction -- `vcvt.f32.s32 s15,s15,#1'
-    {standard input}:58: Error: selected FPU does not support
-      instruction -- `vcvt.f32.s32 s15,s15,#32'
-    {standard input}:136: Error: selected FPU does not support
-      instruction -- `vcvt.f32.u32 s15,s15,#1'
-
-After applying this commit, the valgrind ARM ptests compile without
-errors for tunings:
-  armv7[t][hf][b][-neon] cortexa8[t][hf][-neon]
-where the tuning [option] was successfully compiled, both with
-and without the 'option', and in combination with all other options.
