[libc-commits] [PATCH] D107229: [libc] Add differential and performance targets for sqrtf

[Hedin García via Phabricator via libc-commits]

hedingarcia added a comment.

Yes, comparing the runtime of the sqrt functions from LLVM libc with the system libc:

| function        | perf - LLVM libc | perf - MSVCRT                 |
| sqrtf - Windows | 44.05 sec (44051715500 ns) | 417.84 sec (417843359900 ns) = 6.96 mins |
|



| function      | perf - LLVM libc | perf - glibc     |
| sqrtf - Linux | 30.48 sec (30479458632 ns) | 43.72 sec (43716901527 ns) |
|

And by running the differential test:

| function        | diff                |
| sqrtf - Windows | 0 differing results |
| sqrtf - Linux   | 0 differing results |
|
