test: Avoid errors when cross compile by gcc-8.3/9.2
Browse files Browse the repository at this point in the history 
Cross compiling with gcc-8.3 and gcc-9.2 would cause operand mismatch
error in some tests. The C code of some tests were compiled into
stange instructions. Fixing the error by not running the tests
when using gcc-8.3 and gcc-9.2

fixes #622

the SSE counterpart produces INF if a source value is `0.0`.
As a result, additional treatments should be applied to ensure consistency between the conversion and its SSE counterpart.
## Requirement
We advise developers to utilize sse2neon.h with GCC version 10 or higher, or Clang version 11 or higher. While sse2neon.h might be compatible with earlier versions, certain vector operation errors have been identified in those versions. For further details, refer to the discussion in issue [#622](https://github.com/DLTcollab/sse2neon/issues/622).
## Usage
- Put the file `sse2neon.h` in to your source code directory.
