AddressSanitizer on SPECCPU2006
Hi
If so, is it able to disable this check. All I need is just to get the BB
coverage information
Regards

AddressSanitizer on SPECCPU2006
Hi Alex
Thanks for your email. But it seems not work. I removed the
-fsanitize=address flag.
The global buffer overflow message doesn't show. However, no *.sancov file
is created after I run perlbench. Thus, I could not get the BB coverage. Do
you have any ideas? Many Thanks
Regards
Muhui

AddressSanitizer on SPECCPU2006
Hi
I am using SanitizerCoverage feature supported by clang to get the
basicblock coverage.
my tested binaries are spec cpu2006. I compiled the binary with the option
COPTIMIZE = -O0 -fsanitize=address -fsanitize-coverage=bb -flto
-fno-strict-aliasing -std=gnu89 -gdwarf-3
After the compiling process is end. I run the 400.perlbench. with the
command
ASAN_OPTIONS=coverage=1 ./perlbench.

[LLVMdev] SPEC CPU2006 bitcode files

I'm trying to generate bitcode files from the SPEC CPU2006 benchmark suites.

[LLVMdev] Problem Compiling llvm-gcc 4.2

Dear All,
I have been trying for days but still cannot break this barrier. May I
get your help?
I have compiled llvm-2.1 successfully and make install. When I proceed
with llvm-gcc-4.2-2.1, however, I keep getting linking error as
attached. Some functions with totally different content conflict with
each other in linking process.
That is a Linux box (Debian, with 2.6.23-1

[LLVMdev] make-test dependencies on local directory
These benchmarks are not distributed with llvm (which doesn't have the
legal right to distribute Spec, for example). If you have them from
another source, you need to configure --with-externals=<path>

[LLVMdev] [RFC/PATCH][0/4] New SystemZ backend
Hello,
I'd like to propose the addition of a new SystemZ backend to the LLVM and
Clang code base. We're interested in this for the same reason we've been
interested in the PowerPC back-end recently: to enable packages in upcoming
enterprise Linux distributions that need LLVM support (e.g. 3D desktop
support via llvmpipe).
Now, I understand that a SystemZ backend used to be part of

[LLVMdev] Problem to run SPEC2006
I can't really tell what is happening based on this output, but 'make' is not the right way
to build SPECcpu2006 components. You need to do either by using the supplied 'runspec'
command with '-build' action directive or to issue the 'specmake' (which is a
make adjusted by spec.org) on the build component folder.
I can build 433.milc on PPC64 with clang without

Okay, thanks. Thre should be better warning/error reporting though.

[LLVMdev] Performance problems with FORTRAN allocatable arrays
I've noticed that LLVM does a bad job of optimizing array indexing
code for FORTRAN arrays declared using the ALLOCATABLE keyword.
For example if you have something like the following:
DOUBLE PRECISION,ALLOCATABLE,DIMENSION(:,:,:,:) :: QAV
...
ALLOCATE( QAV( -2:IMAX+2,-2:JMAX+2,-2:KMAX+2,ND) )
...
DO L = 1, 5
DO K = K1, K2
DO J = J1, J2
DO I = I1, I2
II = I +

[LLVMdev] Multiple definitions of _floor_log2
I am trying to build the llvm-gcc frontend. I think I have followed the
directions correctly.
I am using cygwin on XP SP2 (uname -a reports: CYGWIN_NT-5.1 pad7
1.5.25(0.156/4/2) 2007-12-14 19:21 i686 Cygwin)
gcc --version reports: gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using
dmd 0.125)
Since there is no binary for llvm-gcc I am following the directions in
the tar file for the 4.2 version.
