The SPE-EEF system-register only feature introduced in Armv8.7-a adds support for an extra system register (PMSNEVFR_EL1) to the Statistical Profiling extension.

However, SPE-EEF is gated even for Armv8.7-a and the spe-eef subtarget-feature is needed to enable it.

This behavior is inconsistent with the implementation for other system-register only features as they can be used ungated under supported architectures.
(e.g. HCX : Enable Armv8.7-A HCRX_EL2 system register).
GCC/Binutils too do not add command line flags for features that only enable system registers.

Fix by enabling SPE-EEF unconditionally under v8.7-A and above.

Changes

The SPE-EEF system-register only feature introduced in Armv8.7-a adds support for an extra system register (PMSNEVFR_EL1) to the Statistical Profiling extension.

However, SPE-EEF is gated even for Armv8.7-a and the spe-eef subtarget-feature is needed to enable it.

This behavior is inconsistent with the implementation for other system-register only features as they can be used ungated under supported architectures.
(e.g. HCX : Enable Armv8.7-A HCRX_EL2 system register).
GCC/Binutils too do not add command line flags for features that only enable system registers.

Fix by enabling SPE-EEF unconditionally under v8.7-A and above.

[AArch64][v8.7-A] Fix inconsistency in SPE_EEF feature (llvm#115296)
86beef1 
The `SPE-EEF` system-register only feature introduced in Armv8.7-a adds
support for an extra system register (`PMSNEVFR_EL1`) to the Statistical
Profiling extension.

However, `SPE-EEF` is gated even for Armv8.7-a and the `spe-eef`
subtarget-feature is needed to enable it.

This behavior is inconsistent with the implementation for other
system-register only features as they can be used ungated under
supported architectures.
(e.g. HCX : Enable Armv8.7-A `HCRX_EL2` system register).
GCC/Binutils too do not add command line flags for features that only
enable system registers.

Fix by enabling `SPE-EEF` unconditionally under v8.7-A and above.
