Hi Eric, I'm using gcc. My make command is make -j9 as mentioned earlier, the -cc1 switch did the trick for me.

Hi all, I currently have a problem setting up gdb with clang/llvm. I configured llvm/clang (trunk) with: ../llvm/configure --prefix=PROJECT_DIR/install_debug --enable-expensive-checks --enable-targets=host --enable-debug-runtime --enable-shared Now, when I invoke gdb with the freshly built clang it basically works. I can look at backtraces, set breakpoints and so on but breakpoints are never

...solves the problem for me. As I learned from the last email, specifying -v is a good starting point in order to see what actually is happening and tackle such problems. -- Roland ----- Original Message ----- > From: "Jim Grosbach" <grosbach at apple.com> > To: "Roland Leißa" <leissa at cs.uni-saarland.de> > Cc: LLVMdev at cs.uiuc.edu > Sent: Montag, 23.

...cpp a Clang source file? If so, make sure you run the compiler itself with "clang -cc1", not the compiler *driver* with bare "clang". See here ( http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-March/020275.html ) for a similar question. -Matt On 04/13/2012 04:19 PM, Roland Leißa wrote: > Hi all, > > I currently have a problem setting up gdb with clang/llvm. > > I configured llvm/clang (trunk) with: > ../llvm/configure --prefix=PROJECT_DIR/install_debug --enable-expensive-checks --enable-targets=host --enable-debug-runtime --enable-shared > > Now, wh...

Hi all, I'm currently working on an extension for clang. Apparently, I'm doing sth incorrectly currently. The Verify complains with Wrong type for attribute signext <8 x i32> (<256 x i1>, i16, <2 x double>)* @_Z4testsDv2_d Now, this information is not that useful. Is it possible to emit this "broken" llvm code in order to better understand what went wrong? --

Hi all, I've just written a small enhancement to SimplifyPHINode. The idea is the following: If we have this: a = phi(X, X, undef, undef, X, undef) X = select cond, sth, a or this: a = phi(X, X, undef, undef, X, undef) X = select cond, a, sth we can replace the phi by 'a' and the select by 'sth'. Why does this work? Well, in those cases where control-flow happens to

Hi all, is there a portable and effective way of emitting code which checks whether all vector elements are true or false? Currently, I'm doing this: %sext = sext <4 x i1> %my_cmp to <4 x i8> %bcast = bitcast <4 x i8> %sext to i32 %all_zeros = icmp ne i32 %bcast, 0 br i1 %all_zeros, label %A, label %B The emitted code works, but it's not great. I'd like

I consider my patch not mature enough to be committed. I just wanted to hear what others are saying. I'm not quite sure how to exactly deal with these cascades of selects which induce a cycle via a Phi; I'd like to implement that as well. Also, I'm not sure whether InstructionSimplify.cpp is the proper place for this optimization. -- Roland ----- Original Message ----- > From:

Hi all, I'm currently using llvm::TrackingVH in order to have a tracking reference to a definition. Unfortunately, TrackingVHs are incredibly slow. Are there alternatives? -- Roland

Hi Duncan, thanks for the hint. I tried both variants: define <4 x float> @masked_add_1(<4 x i1> signext %mask, <4 x float> %a, <4 x float> %b) define <4 x float> @masked_add_32(<4 x i32> %mask, <4 x float> %a, <4 x float> %b) Unfortunately, this will raise an assertion: Wrong types for attribute: zeroext signext noalias nocapture sret byval nest

Hi all, how can I retrieve the data layout of the host machine? Thanks for helping out, Roland

Hi all, I'm currently trying to figure out the best way to pass vector of booleans to other functions. Take this small example: define <4 x float> @vcmp_add(<4 x float> %a, <4 x float> %b) { entry: %cmp = fcmp olt <4 x float> %a, %b %add = fadd <4 x float> %a, %b %sel = select <4 x i1> %cmp, <4 x float> %add, <4 x float> %a ret <4 x
