Just a quick question on LLVM, signals, and the lli interpreter. A sample program is included at the end. Platform is x86, Linux, 32-bit, GCC 4.2.4. Does lli -force-interpreter support signals, or is it only the JIT that does? The following sample program crashes with lli 2.5 and lli top-of-tree. Thanks and regards, Matt ============================= #include <stdio.h> #include

Hello, The binaries produced by LLVM and other compilers divide code up into various sections, e.g. the .text section. What is the recommended approach to assigning a symbol the address of a section using LLVM? Using GCC/LD, you can do this with a linker script, e.g. in a linker script you can do: _text = .; _stext = .; These symbols are then available in the corresponding C code using an

If so, I'm interested in the approach taken so as to avoid wasting time. Thanks and regards, Matt Renzelmann

Andrew, Eli, thank you both for your help. You both proposed essentially the same idea at the same time and it works fine. I appreciate your assistance thus far. I'd set this aside for a few days to work on another thing, but am back now and have another question. User mode Linux contains a "__syscall_stub" code section. The linker script defines it to be page-aligned, and it

Thank you for your reply--I've now done that. Unfortunately, there's a new error now: ------------ Cannot yet select: intrinsic %llvm.test_intrinsic test.c:25: internal compiler error: Aborted Please submit a full bug report, with preprocessed source if appropriate.

Hello, As an experiment, I'm simply trying to add a trivial intrinsic to LLVM, but I'm having trouble, which suggests that I'm overlooking the obvious ;) Platform is GCC-4.2.4/LLVM from SVN/x86. First, I've read the page here about 10 times, so I'll speculate that my reading comprehension is lacking: http://www.llvm.org/docs/ExtendingLLVM.html Code I've added to the

Hello, Platform is RHEL5, GCC 4.2.4, x86-32, and LLVM/LLVM-GCC from subversion (yesterday evening). I'm compiling C code into bitcode, and then executing the bitcode using the JIT compiler (lli). I've managed to reproduce a problem when multiple signals go off around the same time. A sample program is below. The result is the "recursive compilation detected" JIT compiler
