[llvm] [Darwin] Fix availability of exp10 for watchOS, tvOS, xROS. (PR #98542)

[Florian Hahn via llvm-commits]

https://github.com/fhahn created https://github.com/llvm/llvm-project/pull/98542

Update availability information added in 1eb7f055d9a. exp10 is available on iOS >= 7.0 and macOS >= 10.9. On all platforms, it is available on any version. Also drop the x86 check, as the availability only depends on the OS version, not the target platform.

Subject: [PATCH] [Darwin] Fix availability of exp10 for watchOS, tvOS, xROS.

Update availability information added in 1eb7f055d9a. exp10 is available
on iOS >= 7.0 and macOS >= 10.9. On all platforms, it is available on
any version. Also drop the x86 check, as the availability only depends
on the OS version, not the target platform.
