Neon is not supported by armv5, disable the simd extension build.

Drop this comment. Neon may be missing from other ISA levels too (i.e.
this fix is not specific to armv5).

Get it. Thanks.

Shouldn't this be checking for neon in TUNE_FEATURES rather than
TUNE_CCARGS_MFPU?

Refer feature-arm-vfp.inc:

TUNE_CCARGS_MFLOAT = "${@ bb.utils.contains('TUNE_FEATURES',
'callconvention-hard', 'hard', 'softfp', d) if
(d.getVar('TUNE_CCARGS_MFPU') != '') else '' }"

TUNE_CCARGS   .= "${@ ' -mfloat-abi=${TUNE_CCARGS_MFLOAT}' if
(d.getVar('TUNE_CCARGS_MFLOAT') != '') else ''}"


There are condition that neon is not in TUNE_FEATURES, but vfp is in it.
so TUNE_CCARGS may append -mfloat-abi=softfp,  then

simd module here can be compiled  sucessfully.

The SIMD code can only be used on targets which support neon. There
may be other cases where the code can be compiled but if it can never
be used at run time it's not very useful.

OK, thanks. I will send V3 patch.



It should also probably be conditional on the _arm
over-ride since neon will be missing from
TUNE_CCARGS_MFPU/TUNE_FEATURES for other architectures.Since big
endian ARM doesn't use the _arm over-ride you will also need a
duplicate line with the same logic with the _armeb override too. See
the lines below which do the equivalent for _powerpc / _powerpc64 as a
reference.

ok. thanks.

[OE-core] [V2][PATCH] libjpeg-turbo: fix do_compile error on armv5

2021-06-09 Thread Changqing Li 
From: Changqing Li 

fix below error:

soft-float ABI. Please use -mfloat-abi=softfp or -mfloat-abi=hard"
31 | #error "NEON intrinsics not available with the soft-float ABI. Please use 
-mfloat-abi=softfp or -mfloat-abi=hard"

Neon is not supported by armv5, disable the simd extension build.
