From 13df462691745d7f99c6ba0b0c26dc95eda16b73 Mon Sep 17 00:00:00 2001 From: Matt Arsenault Date: Sun, 10 Nov 2013 02:04:09 +0000 Subject: Allow multiple check prefixes in FileCheck. This is useful if you want to run multiple variations of a single test, and the majority of check lines should be the same. llvm-svn: 194343 --- llvm/docs/CommandGuide/FileCheck.rst | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'llvm/docs/CommandGuide/FileCheck.rst') diff --git a/llvm/docs/CommandGuide/FileCheck.rst b/llvm/docs/CommandGuide/FileCheck.rst index a71007b6161..5a60d60ae3d 100644 --- a/llvm/docs/CommandGuide/FileCheck.rst +++ b/llvm/docs/CommandGuide/FileCheck.rst @@ -30,11 +30,13 @@ OPTIONS .. option:: --check-prefix prefix - FileCheck searches the contents of ``match-filename`` for patterns to match. - By default, these patterns are prefixed with "``CHECK:``".
