test: Avoid errors with gcc prior to 10 (#625)
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
unexpected instructions. Fixing the error by not running the tests with
gcc prior to 10.

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
Developers are advised 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.
