From 27aff8755b33bfa59a22126fcd7f700d0fdde8db Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Sun, 8 Jun 2008 20:18:35 +0000 Subject: [PATCH] Using llc always rather than sometimes using LLC. Try to improve language in various places. Use X86 always rather than sometimes using x86. Add some minor Ada info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52095 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/ReleaseNotes.html | 53 +++++++++++++++++++++--------------------- 1 file changed, 27 insertions(+), 26 deletions(-) diff --git a/docs/ReleaseNotes.html b/docs/ReleaseNotes.html index 015564a54d2..3cb9f94bb32 100644 --- a/docs/ReleaseNotes.html +++ b/docs/ReleaseNotes.html @@ -96,7 +96,7 @@ test suite no longer depends on llvm-upgrade, which makes it run faster.
