Thank you, Clayton. It works now! Our debugger server responds "name:J28;generic:fp;bitsize:32;encoding:uint;format:hex;gcc:60;dwarf:60". And I also set other "generic" attributes like sp, pc, ra, arg1~arg8 to related registers. I dig a little and find llvm dwarf generator uses TargetRegisterInfo::getFrameRegister() to obtain frame base, and uses TargetFrameLowering::getFrameIndexReference...

Hi, I'm trying to compile and run the following code-snippet: implementation uint %fie(uint* %x) { %e = getelementptr uint* %x, int 1 ; %f = load uint* %e ret uint 3 } int %main(int %argc, sbyte** %argv) { %z = malloc uint, uint 10 %g = call uint %fie(uint* %z) ret int 0 } But the getelementptr instruction gives a segmentation fault. Have I misunderstoo...

I am creating types through this interface and I get quite a mess seen below. And this is relatively simple. Any ideas? -John alloca { { int, uint, sbyte*, \4* (), \4* (\4*), { { int, uint, sbyte*, \4* (), { { int, uint, sbyte*, \4 (), \4 (\4), \8* (\4), \4 (\4) } }* (\4*), \4* (\4*), \4* (\4*), { { int, uint, sbyte*, \4 (), \4 (\4), \8* (\4), \4 (\4) } }* (\4*), \4* (\4*, \4*), \4* (\4*, { { int, uint, sbyte*, \4 (), \4 (\4), \8* (\4), \4 (\...

Thank you, Clayton. This is very helpful. We use the LLDB specific GDB remote extensions, and our debugger server supports "qRegisterInfo" package. "reg 0x3c" is the frame pointer. In the example mentioned above, we have SP = FP - 40 for current call frame. And variable "a" is stored at address (FP + -24) from asm instruction [FP + -24] = R3;; Thus we can conclude

file://docs/LangRef.html#globalvars The section describing the definition of global vars discusses that you can specify an alignment and can also specify a section. Could someone provide an example that works in gccas in release 1.9 for both defining which section the var is assigned to and defining the variables alignment? Also, is there another document that describes how you define sections

Hi! Hmm, ok. I'm using the 1.2 release. Found out that it worked when using long to index getelementptr, but not when using uint, int or ulong. But then I'll try with the CVS code instead.
