| |
curve25519-x86_64.c fails to build when CONFIG_GCOV_KERNEL is enabled. The error is "inline assembly requires more registers than available" thrown from the `fsqr()` function. Therefore, excluding this file from GCOV profiling until this issue is resolved. Thereby allowing CONFIG_GCOV_PROFILE_ALL to be enabled for x86.
