How hard would it be to compile this pass and add it to the passes that opt can run? Is this something I should be able to do relatively quickly? What was the name of the file(s) that implemented the pass?

Chris: It was in the 1.5 release but not subsequent to that. You can find this by looking for the file in the branches that were converted from subversion. You can find the file you're looking for here: http://llvm.org/viewvc/llvm-project/llvm/branches/release_15/lib/Transforms/Scalar/LowerConstantExprs.cpp?view=log Reid.

What was the name of the file(s) that implemented the pass? It should be easy, modulo it bitrotting. It is already built as an opt pass. The filename was LowerConstantExpr.cpp IIRC. -Chris

Ok. So I took the source code from 1.5 for the LowerConstantExprs pass and (hopefully) corrected all the bitrot. It now compiles. But opt doesn't see it (when I run Release/bin/opt --help it doesn't show up). So, I copy the Transform/Hello directory and compile it as a dynamically loaded pass. When I run Release/bin/opt -load Release/lib/LLVMLowerCons...

How can you see these in viewcv? -Chris -- http://nondot.org/sabre/ http://llvm.org/

...struction). Is there some way to get a new name (like tmp155) and have a high degree of confidence that it is actually unique? -- Ben On 7/4/07, Chris Lattner <sabre at nondot.org> wrote: > On Wed, 4 Jul 2007, Ben Chambers wrote: > > Ok.

...of confidence that it is actually unique? Sure. Just give every name "tmp" and it will autounique them. -Chris > On 7/4/07, Chris Lattner <sabre at nondot.org> wrote: >> On Wed, 4 Jul 2007, Ben Chambers wrote: >>> Ok.

Hi! Is there a pass that will remove constant expressions from appearing within other expressions? For instance it would convert the call: %tmp20 = tail call i32 (i8*, ...)* @printf( i8* getelementptr ([4 x i8]* @.str, i32 0, i32 0), i32 %tmp18 ) ; <i32> [#uses=0] Into: %tmpFresh = getelementptr [4 x i8]* @.str, i32 0, i32 0 ; <i8*> [#uses = 1] %tmp20 = tail call i32 (i8*,
