• configure : arm : Don't add -march= to the compiler if no preference was passed

  20 septembre 2021, par Martin Storsjö

  configure : arm : Don't add -march= to the compiler if no preference was passed
  If no —cpu= option was passed to configure, we detect what the
  
  compiler defaults to. This detected value was then fed back to the
  
  rest of the configure logic, as if it was an explicit choice.
  This breaks on Ubuntu 21.10 with GCC 11.1.
  Since GCC 8, it's possible to add configure extra features via the
  
   march option, like e.g. -march=armv7-a+neon. If the -mfpu= option
  
  is configured to default to 'auto', the fpu setting gets taken
  
  from the -march option.
  GCC 11.1 in Ubuntu seems to be configured to use -mfpu=auto. This
  
  has the effect of breaking any compilation command that specifies
  
   march=armv7-a, because the driver implicitly also adds -mfloat-abi=hard,
  
  and that combination results in this error :
      cc1 : error : ‘-mfloat-abi=hard’ : selected processor lacks an FPU
  One can compile successfully by passing e.g. -march=armv7-a+fp.
  Therefore, restructure configure. If no specific preference was set
  
  (and the 'cpu' configure variable was set as the output of
  
  probe_arm_arch), the value we tried to set via -march= was the same
  
  value that we just tried to detect as the compiler default.
  So instead, just try to detect what the compiler defaults to, with
  
  to allow setting other configure settings (such as 'fast_unaligned'),
  
  but don't try to spell out the compiler's default via the -march flag.
