Subject: [PATCH 0/2] Remove some i386 system call optimizations
Date: Tue, 11 Jan 2022 11:05:08 +0100	[thread overview]
Message-ID: <cover.1641895400.git.fweimer@redhat.com> (raw)

The configure check for CAN_USE_REGISTER_ASM_EBP is unreliable.  And we
used it to switch away from using %ebx in assembler constraints, but
this appears to be no longer necessary.

Tested on i686-linux-gnu.  Built with build-many-glibcs.py.

Thanks,
Florian

  i386: Always treat %ebx as an allocatable register
  i386: Always use __libc_do_syscall for 6-argument syscalls (bug 27997)
