Hi.

It's a small fix that removes the first commit from the following command:

$ git svn-rev 279550
commit bcf3fa7cf5a3d024b507f68ffdfab037f4820781
Author: Andre Vieira <andre.simoesdiasvieira@arm.com>
Date:   Wed Jan 29 14:23:22 2020 +0000

     IRA: Revert 11b8091fb to fix PR 93221
     
     A previous change to simplify LRA introduced in 11b809 (From-SVN: r279550)
     disabled hard register splitting for -O0. This causes a problem on aarch64 in
     cases where parameters are passed in multiple registers (in the bug report an OI
     passed in 2 V4SI registers). This is mandated by the AAPCS.

Ok, thanks.

Thanks, this matches the commit hook (which only rejects From-SVN: at 
start of line, not elsewhere in a commit message).
