similar to: Help with bitcast instruction

Hi Tim, I'm still struggling on the instruction: call void bitcast (void (%struct.png_struct_def.68*, i8*, i8* (%struct.png_struct_def.68*, i64)*, void (%struct.png_struct_def.68*, i8*)*)* @png_set_mem_fn to void (%struct.png_struct_def*, i8*, i8* (%struct.png_struct_def*, i64)*, void (%struct.png_struct_def*, i8*)*)*)(%struct.png_struct_def* %create_struct, i8* %mem_ptr, i8*

Hi all, I have seen in multiple cases that, usually at the beginning of the function. if a BranchInst is encountered the next block might have %0 indicated as predecessor. I think it is a way to say "no predecessors found". Am I correct? Few examples just for clarifying what I mean: define noalias %struct.png_struct_def* @png_create_read_struct_2(i8* %user_png_ver, i8* %error_ptr, void

Hi all, I have encountered a weird case that I cannot understand. Inside the visitStoreInst I have a reference (F) to the function png_set_mem_fn. If I do F->dump() i can set the IR of that function correctly e.g.: ; Function Attrs: nounwind uwtable define void @png_set_mem_fn(%struct.png_struct_def.68* noalias %png_ptr, i8* %mem_ptr, i8* (%struct.png_struct_def.68*, i64)* %malloc_fn, void

Hi all, I have managed to compile libpng using wllvm and obtain the IR of pngpixel ( small tool which is part of libpng ). libpng has a function called png_check_IHDR: void /* PRIVATE */ png_check_IHDR(png_const_structrp png_ptr, png_uint_32 width, png_uint_32 height, int bit_depth, int color_type, int interlace_type, int compression_type, int filter_type) { int error = 0; /*

Hi David, My question is: why both #ifdef and #else branches are missing? I think at least one of the two should be present... In fact there is a case where the width could be greater then PNG_USER_WIDTH_MAX but not greater then PNG_UINT_31_MAX. That's why I was expecting at least one of the two...

Below is a patch to get rid of several warnings which occur while building syslinux 3.07 with the current gcc 4 snapshot. This fixes all the warnings except one unused variable. Take them or leave them as you see fit. They're all com32 stuff that's pulled in from external sources. --- syslinux-3.07/memdisk/unzip.c.gcc4 2004-12-07 23:29:22.000000000 -0500 +++

David, sorry for this email but I noticed I made a mistake in the previous one. So I managed to compile llvm Debug with asserts release. I have used the following commands: cmake -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_ENABLE_RTTI=ON -DLLVM_ENABLE_FFI=ON -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_ASSERTIONS=ON .. cmake --build . -- -j8 && sudo cmake --build . --target install Once lli was

> > Hey Lang - does any of this look familiar to you? I'm afraid not: I know nothing about the interpreter. As far as I'm aware it's essentially abandonware. Alberto: The usual recommendation in these circumstances is to use a JIT class instead of the interpreter. You're using -force-interpreter though, so I assume you really want to use the interpreter for your use case?

Hi David, Thanks for the suggestions. I can definitely provide the example bc file and image ( please see the attachments ). For the debug + asserts I need a bit of more time. Anyway the full output of lli is: lli --force-interpreter examples/pngpixel_crash.bc 0 0 examples/mini.png png_ptr->width: 1 max_pixel_depth: 24 row_bytes: 28 Unknown constant pointer type! UNREACHABLE executed at

Hi David, In pretty sure that the crash is due to the instruction I have shared in my first email. In order to run pngpixel you just need libpng and zlib.. honest I thought that the .bc had Al the necessary. I'm happy to help you to reproduce it. As a curiosity, why do you think you cannot reproduce it? Unfortunately I won't be able to modify the interpreter soon.. anyway, I'll try to

Hi Alberto, Can you please file a bug for it, with the test case attached (if you haven't already). Thanks, Ehud.

Hi all, as usual I'm playing with the Interpreter and unfortunately I hit a crash. I have narrowed down the problem an the crash happens inside the inflate function which is part of zlib and specifically at the instruction: store <2 x %struct.code*> <%struct.code* getelementptr inbounds ([512 x %struct.code], [512 x %struct.code]* @fixedtables.lenfix.681, i64 0, i64 0), %struct.code*

Patches 1-4 are basically uncontroversial, straightforward refactoring and IMHO we should just push them. Possibly 1-3 should be squashed together, but I posted them separately so they are easier to review. Patches 5 and 6 together implement OClosure. Patch 5 adds the feature and is simple to understand. Patch 6 changes the Closure completion callbacks into OClosure, but because it doesn't
