From 6813c15e1d1946b634232018d77e51688ead704c Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Fri, 20 Jul 2007 20:14:52 +0000 Subject: [PATCH] No longer referencing "shared memory" as this can confuse people. The memory is clearly shared between processors if these instructions are being used, no further specification of what type of memory is necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40118 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/LangRef.html | 26 +++++++++++++------------- 1 file changed, 13 insertions(+), 13 deletions(-) diff --git a/docs/LangRef.html b/docs/LangRef.html index a45aba896b3..6ebbb293077 100644 --- a/docs/LangRef.html +++ b/docs/LangRef.html @@ -4841,7 +4841,7 @@ Handling document.

Just as hardware provides a "unviresal IR" for source + hardware behavior. Just as hardware provides a "universal IR" for source languages, it also provides a starting point for developing a "universal" atomic operation and synchronization IR.
