From be8cc2a3dedeb7685f07e68cdc4b9502eb97eb2b Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Wed, 29 Apr 2009 00:15:41 +0000 Subject: Second attempt: Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70343 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/CommandGuide/llc.pod | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'docs/CommandGuide') diff --git a/docs/CommandGuide/llc.pod b/docs/CommandGuide/llc.pod index f5fd34f01a..eba7859e28 100644 --- a/docs/CommandGuide/llc.pod +++ b/docs/CommandGuide/llc.pod @@ -41,6 +41,12 @@ Other B options are as follows: Print a summary of command line options. +=item B<-O>=I + +Generate code at different optimization levels.
