   4 Subject: [PATCH] use appropriate -march/-mcpu/-mfpu for ARM test apps
   5
   6 Ensure that test apps in none/tests/arm are compiled with appropriate
   7 -march/-mcpu/-mfpu flags to support the instructions being tested.
   8 The aim is to build all tests, even ones which may not run correctly
   9 on all target CPUs.
  10
  11 For tests requiring armv7ve instructions, ensure that we set both
  12 -march=armv7ve and -mcpu=cortex-a15 (since some TUNE_CCARGS may set
  13 -march=armv7-a and adding -mcpu=cortex-a15 alone is not enough to
  14 over-ride that).

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