Hi, When running my own lld generated library/executable I'm getting: LD_LIBRARY_PATH=. ./ConsoleApplication347 ./ConsoleApplication347: symbol lookup error: ./ConsoleApplication347: undefined symbol: (theres nothing after undefined symbol) How can I figure out what's I'm doing wrong?

When linking a project with lld, the android libc links to __executable_start which isn't defined when linking with lld (tried on x86), but is when linking with gnu ld it seems. I tried: .globl __executable_start __executable_start = __ehdr_start as a workaround but seems to be ignored. Anyone know a better workaround? Thanks, -- Carlo Kok RemObjects Software

Android libc casts its address to the elf header type. So I think start of text?

Dear all, Assume that I have an S4 class "MyClass" with a slot "myname", which is initialized to: myname="" in method("initialize"): myclass <- new("MyClass", myname="") Assume that class "MyClass" has a method "mymethod": "mymethod.MyClass" <- function(object, myname=character(0), ...) {

When compiling code with lld -O0 --lto-O0 --eh-frame-hdr I get strange interleaved line info all over the place: ... 0x00000000000595ac 22 11 1 0 0 is_stmt 0x00000000000595bc 25 7 1 0 0 is_stmt <<< 0x00000000000595c0 22 11 1 0 0 is_stmt 0x00000000000595c4 25 7 1 0 0 is_stmt <<< 0x00000000000595c8 26 7 1 0 0 is_stmt but the code only has 1 reference to line 25 and the

Hi, Is there any way to debug the codeview output of llvm from within Visual Studio? I want to use the codeview line info debug output of clang/llvm. I tried with the x86_64-pc-windows-msvc and i686-pc-windows-msvc triples and linking it into an existing project with VC++ from within the IDE and outside with link /debug. Neither option lets me debug with Visual Studio as debugger host.

Thanks! Unfortunately this doesn't seem to cause it, because when I fix it to match the other files (and pretty much how clang emits it:) !0 = !DIGlobalVariableExpression(var: !1, expr: !DIExpression()) !1 = !DIGlobalVariable(name: "IDispatch_UID", linkageName: "f_t2b_RemObjects_d_Elements_d_System_d_____Global.IDispatchUID", scope: !2, file: !3, type: !622, isLocal:

I'd be happy to review your patches too! Thanks. Looks like it's likely that it's one of the 0xF1 sections, the first one always has the object file name and what seems

I have @_rtti_a_a = linkonce_odr constant in two files that end up as coff object files. Shoudln't the linkonce_odr prevent duplicate symbol: __rtti_a_a \consoleapplication149.o and __rtti_a_a island.lib(island.o) from happening in LLD? If not what alternative can I use? THis is used for template like generics, so having duplicate functions and globals is going to happen a lot) (Side

Hi, I have a function with: attributes #2 = { "no-frame-pointer-elim"="true" "no-frame-pointer-elim-non-leaf" } Yet when compiling it generates: https://gist.github.com/carlokok/7c3c98d2fd8c966671f40a5ad94f19d3 (Note how it checks fFinalizer before setting up ebp).

Yep, it's once again variable and it's type using different scopes.

Hi Carlo, Do you have VS2010 handy? It should read the DI fine. Unfortunately, VS2013 is not able to use the debug info we generate.
