Thanks Teresa Yes it is astar, happen to send a tar of the sources but they are just copies from the spec distribution The ld command is: GNU ld (GNU Binutils) 2.29.1 Thanks for the guidance on path names. The prefix-replace just effects the string written to the object files right? So we could post-process that file with other tools as well, correct? Thanks again --david From: Teresa Johnson

Fails with gold too: Library-native.o:Library.cpp:regway: error: undefined reference to 'vtable for regwayobj' /home/dcallahan/fbsource/fbcode/third-party-buck/platform007/tools/binutils/bin/gold/ld: the vtable symbol may be undefined because the class is missing its key function clang-8: error: linker command failed with exit code 1 (use -v to see invocation) From: Teresa Johnson

Thanks Jonas, I wasn't aware of the gold linker plugin. Here's what I do, in my current workflow. First, I use clang to compile each .c file (e.g. for the bzip2 benchmark, or any other) into a .bc file: specmake clean 2> make.clean.err | tee make.clean.out rm -rf bzip2 bzip2.exe *.o *.fppized.f* find . \( -name \*.o -o -name '*.fppized.f*' \) -print | xargs rm -rf

Hi, It was suggested that I post my question regarding a LLVM 3.4 performance regression to this mailing list, rather than stackoverflow. So here is the link: https://stackoverflow.com/questions/22902034/llvm-3-4-performance-regressed Thanks :) Jens -- Jens Tröger http://savage.light-speed.de/

Hi, in lib/Analysis/RegionPass.cpp there are 3 occurrences of: CurrentRegion->getNameStr() These are slowing down compile times with polly. I would suggest to either remove these calls, or only turn on when the programmer asks for -debug. The reason for the slow pretty printing of types is the same as previously discussed in: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-July/063755.html

Hi, I am trying to compare the loop vectorizers effectiveness for different targets relative to each other. That way, I am hoping to find loops that are not vectorized - but could be - on my target by finding other targets doing this successfully. With some luck, there might be something in the Target files that could be fixed with improved vectorization as a result... I would like to do

I am looking for advice on a problem observed with -fprofile-sample-use for samples built with the AutoFDO tool I took the "hmmer" benchmark out of SPEC2006 It is initially compiled clnag++ -o hmmer -O3 -std=gnu89 -DSPEC_CPU -DNDEBUG -fno-strict-aliasing -w -g *.c This baseline binary runs in about 164.2 seconds as reported by "perf stat" We build a sample file from this

I haven't seen anything this strange, and it's 100% reproducible. I'm hoping that there are some clever ideas out there for what to look for, since I can test to my heart's desire on this one... My Dad lives in Florida, and has a Bellsouth DSL line. Of course, he has a regular POTS line connected on the same line. He has the appropriate filters on every jack that has a phone

Hello LLVM, I encountered the following bugs when I compiled my program in debug version. Could someone help me with that ? Really appreciate that. Thanks, Take the mcf program in SPEC2K6 as example. The compiling options are : clang -O0 -c -emit-llvm -o obj/mcf.o -g -DSPEC_CPU mcf.c llvm-link -o mcf.bc obj/mcf.o opt -o mcf.opt.bc mcf.bc -O2 llc -O0 -relocation-model=static -o mcf.s

I was wondering if anyone knew of some resources I could look at to learn about how rails works internally. I''ve been looking through the code but I was wondering if there were any high level explanations of how it works overall.

What do you mean by test case please ? Using the following commands to compile mcf program can reproduce such issue all the time. Probably it is my version's problem. Because I checked out 3.3version from SVN before published. Could you tell me where Manman modified ? I cannot port to new version very quickly after changing it a lot already.

Hey all, I've run accross what seems to be a bug in the recordPlot/replayPlot functionality (or at least the lack of a feature which seems pretty reasonable to expect to be there) When drawing to a file-based graphics device (I tested with png()), the file resulting from calling replayPlot on a recordedplot object does not contain an identical image to that captured by the same graphics

This is from work that Manman did. I thought she'd fixed this particular issue though. Can you file a bug with a test case please?

From: Nicholas Bellinger <nab at linux-iscsi.org> This patch follows MST's recommendation to move checks for vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations from MemoryListener->region_[add,del]() -> vhost_set_memory() into final MemoryListener->commit() -> vhost_commit() callback.

Hi, What version of clang are you using? I think r174785 is the fix. Manman On Tue, Nov 5, 2013 at 11:04 AM, lipengcheng <pli at cs.rochester.edu> wrote: > What do you mean by test case please ?

>> Can someone else try to reproduce this? I tried gcc.c from http://people.csail.mit.edu/smcc/projects/single-file-programs/ and the difference is a bit more noticeable: -O0 -mno-relax-all real 0m13.182s user 0m12.690s sys 0m0.450s -O0 gcc.o is 10932968 bytes. real 0m12.969s user 0m12.520s sys 0m0.410s gcc.o is 11410552 bytes IMHO it would still be reasonable to switch to
