[MIPS] Improve branch prediction in ll/sc atomic operations. 2007-02-13T22:40:50+00:00 Ralf Baechle ralf@linux-mips.org 2006-09-28T00:45:21+00:00 f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f Now that finally all supported versions of binutils have functioning support for .subsection use .subsection to tweak the branch prediction I did not modify the R10000 errata variants because it seems unclear if this will invalidate the workaround which actually relies on the cheesy prediction of branch likely to cause a misspredict if the sc was successful.

I did not modify the R10000 errata variants because it seems unclear if
this will invalidate the workaround which actually relies on the cheesy
prediction of branch likely to cause a misspredict if the sc was
successful.
