In the following IR module: – define i8 @foo() #0 { entry: %call0 = call i8 @bar() ret i8 %call0 } declare i8 @bar() #1 – @bar() gets marked as its own user in top-of-tree LLVM. I patched the Verifier to check it (but didn’t commit the patch): – Index: lib/IR/Verifier.cpp =================================================================== --- lib/IR/Verifier.cpp (revision 203468) +++

For LLDB I'm writing a dumb module pass that removes all global variables, by running the following code: bool erased = true; while (erased) { erased = false; for (Module::global_iterator gi = llvm_module.global_begin(), ge = llvm_module.global_end(); gi != ge; ++gi) { GlobalVariable *global_var =

The attached patch implements simple target-specific AsmLexers for ARM and Thumb. They are shallow subclasses of a common tokenizer that uses a std::map of register names to IDs to recognize register names, and reports those as AsmToken::Register tokens instead of identifiers. I intend to use the ARM and Thumb AsmLexers as part of an extension of the EnhancedDisassembly library, which provides

I was away doing other things for a while, but I have an API patch separated out, which (in addition to being much smaller than past megapatches) corrects two issues Chris identified in his most recent set of patches: - First, it makes the API a good deal simpler. Now, you can instantiate a single MCDisassembler and, each time you want an instruction disassembled, you can simply pass

Dear mailing list: the attached diff implements a table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit incarnations), integrated into the MC framework. The disassembler is table-driven, using a custom TableGen backend to generate hierarchical tables optimized for fast decode. The disassembler consumes MemoryObjects and produces arrays of MCInsts, adhering to the

Bill, thanks for your comments. I'll respond to them individually. I've attached a new revision of the patch that addresses them. Patch built and tested against SVN 79487, with the additional attached fix that fixes an Intel table bug. Sean On 2009/08/18, at 0:57, Bill Wendling wrote: > 0. Watch out for tabs! Fixed.
