Hello all, I've run into a problem with returning a struct on Linux x86. Consider the following two pieces of code: # cat a.ll declare { i32, i32 } @foo(i32, i32, i32) define void @do_foo() { call { i32, i32 } @foo(i32 1, i32 2, i32 3) ret void } # cat b.c #include <stdio.h> #include <stdint.h> extern void

Hi all, the LLVM documentation lists the 'appending' linkage for having the linker combine two arrays. I'm wondering though if it's then possible to get the size of the combined array, e.g., for iterating over its elements? Or how would I otherwise use the combined array?

Am I missing something?

I'd like to represent strings "Pascal-style" with a length field followed by the actual bytes. Reading the reference manual, I think using a zero-length array should work in a struct like this: { i32, [0 x int8] } However, I get a problem with referencing constants. The following code doesn't compie: @foo = constant { i32, [3 x i8] } { i32 3, [3 x i8]

Sorry for the spam, but we're looking for a postdoc with compiler expertise, and in particular LLVM, for ICSI's networking group. I thought this list might have somebody interested in such a position: http://www.icsi.berkeley.edu/about/netjob.html Feel free to forward further.

It seems that llvm-ld is stripping debugging symbols even with optimizations disabled: > cat main.c int main() { int a = 42; return a; } > clang -c -g -emit-llvm -o main.bc main.c > llvm-ld -disable-opt -b=a.out.bc main.bc > clang -g a.out.bc -o a.out >gdb a.out [...] (gdb) break main Breakpoint 1 at 0x40045b:
