Hi Ed, I wrote http://reviews.llvm.org/D10952 to address your last problem. There is also the related http://reviews.llvm.org/D10918 by Denis to address how you can directly assign sections to segments in the script. Both are in code review.

I was hoping to not have to build LLVM myself, especially on Windows. Can anybody help me with the Windows installer? Failing that, I find the directions for how to compile on Windows hard to follow? Can I build using Cygwin?

...ker script testing, with your example? Alternatively, you can modify lld/test/elf/linkerscript/sections-with-wildcards.test to test your case. This will make your patch complete and ready for commit, and will ensure we do not regress on this bug if this code is ever rewritten.

Hi all, Which are the command-line options available to pass linker script, library path etc.. to lld? I see minimal options listed, when i say, lld -flavor gnu -help Thanks in advance, -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I was interested in trying out LLVM BOLT and generated profile data using Linux perf using the following: perf record -e cycles:u -o perf.data <command> This is without the use of LBR so I understand the performance improvements may not be much but this was more for becoming familiar with BOLT's commands. I then run: perf2bolt -nl -p perf.data -o perf.fdata <binary> and I

Hi, I've encountered a newly introduced bug in lld today. I am building my program with clang and lld on an X86-64 Ubuntu Linux machine. Command line: clang main.c The compiled program invokes the "main" function multiple times until it closes with a segmentation fault. This affects even the most primitive programs like "int main() { return 0; }". The problem

Hi All, Congratulations on the major progress on the llvm linker lld over the past year including the new linker script support. This really makes it possible to ditch binutils altogether. It looks like lld's MEMORY sections are currently parsed but not evaluated, but so far that hasn't been a problem. The only snag is I can't figure out how to define the start of the .data section

...when lowering to machine code. An example: %3 = fcmp %1, %2 %6 = fcmp %4, %5 %7 = and %3, %6 %8 = and %7, %foo Sometimes you'll be screw if you want to play reassociate %7 and %8. I don't see a easy way of catching them in theorem provers.

Hello, I am in a developing process for a new llvm backend (target). Can I create the new target subdirectory out of source. My point is that I want to create a separate svn repo only for my new backend directory and use the llvm project as an external repository. I have to amke some changes to llvm project, to integrate my backend to the llvm, but I won't commit my changes to the llvm

Hello. In order to detect a problem in the initial selection DAG creation that I have in my back end I need to output detailed debug info from the SelectionDAG.cpp module with all the TableGen records that are being processed, and compare between a working back end and my buggy back end. I can debug by adding myself DEBUG() statements in the visit*() methods of the SelectionDAG.cpp

Hi, I've found a crash in lld when using linker script with wildcard matching. An example linker script: INPUT(os/main.o os/foo.o os/startup.o) OUTPUT(k.bin) SECTIONS { . = 0x0 .text : { *startup.o (.text) } .text.2 : { *(.tex*) } } I've wrote up a patch to fix this crash.

I’m trying to install LLVM-3.6.0-r218288-win32.exe on Windows 7 Ultimate x64. The install doesn’t complain, but the toolset doesn’t show up in either Visual Studio 2013 or Visual Studio 2010. Also I selected the choices to add LLVM to the path for every user and put an LLVM icon on the desktop. Neither of this happened. Can anyone tell me how to get this to work? Regards, Eric Mader

...he function, and another containing the cold blocks? The linker would have less flexibility in placement, but maybe it doesn't actually need that flexibility?
