Subject: [PATCH] Fix compilation error raised by vqtbl1q_u8 instruction
|
||
MIME-Version: 1.0

The compilation in Buildroot for the raspberrypi3_qt5we_defconfig
|
||
configuration:
|
||
|
||
make raspberrypi3_qt5we_defconfig
|
||
make
|
||
|
||
raises the following error:
|
||
|
||
In file included from buildroot/output/build/snappy-1.2.1/snappy.cc:29:
|
||
buildroot/output/build/snappy-1.2.1/snappy-internal.h: In function ‘snappy::internal::V128 snappy::internal::V128_Shuffle(V128, V128)’:
|
||
buildroot/output/build/snappy-1.2.1/snappy-internal.h:109:10: error: ‘vqtbl1q_u8’ was not declared in this scope; did you mean ‘vtbl1_u8’?
|
||
109 | return vqtbl1q_u8(input, shuffle_mask);
|
||
| ^~~~~~~~~~
|
||
| vtbl1_u8
|
||
make[4]: *** [CMakeFiles/snappy.dir/build.make:118: CMakeFiles/snappy.dir/snappy.cc.o] Error 1
|
||
|
||
As reported by [1], the vqtbl1q_u8 instruction is supported by A64
|
||
architectures. For this reason, the patch enables the use of the
|
||
instruction only for NEON of such architecture.
