From 7bdf6b00e04c177f22133b5d4be10cb246cb1e76 Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Sat, 5 Jan 2013 11:43:11 +0000 Subject: Convert the TargetTransformInfo from an immutable pass with dynamic interfaces which could be extracted from it, and must be provided on construction, to a chained analysis group. The end goal here is that TTI works much like AA -- there is a baseline "no-op" and target independent pass which is in the group, and each target can expose a target-specific pass in the group. These passes will naturally chain allowing each target-specific pass to delegate to the generic pass as needed. In particular, this will allow a much simpler interface for passes that would like to use TTI -- they can have a hard dependency on TTI and it will just be satisfied by the stub implementation when that is all that is available. This patch is a WIP however. In particular, the "stub" pass is actually the one and only pass, and everything there is implemented by delegating to the target-provided interfaces. As a consequence the tools still have to explicitly construct the pass. Switching targets to provide custom passes and sinking the stub behavior into the NoTTI pass is the next step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171621 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/opt/opt.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'tools/opt') diff --git a/tools/opt/opt.cpp b/tools/opt/opt.cpp index 9c9e394043..c2987f19ed 100644 --- a/tools/opt/opt.cpp +++ b/tools/opt/opt.cpp @@ -658,8 +658,8 @@ int main(int argc, char **argv) { std::auto_ptr TM(Machine); if (TM.get()) { - Passes.add(new TargetTransformInfo(TM->getScalarTargetTransformInfo(), - TM->getVectorTargetTransformInfo())); + Passes.add(createNoTTIPass(TM->getScalarTargetTransformInfo(), + TM->getVectorTargetTransformInfo())); } OwningPtr FPasses; -- cgit v1.2.3
