[Bug rtl-optimization/58493] New: loop is not correctly optimized with O3 and AVX
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58493
Bug ID: 58493
Summary: loop is not correctly optimized with O3 and AVX
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: vgrebinski at gmail dot com
Host: Debian 3.9.6-1 x86_64 GNU/Linux; Intel(R) Xeon(R) CPU
E5-2687W
Target: amd64/sandy bridge
The following example (simplified from a proprietary numerical quant library
issue) shows that AVX loop optimizer mis-compiles code below with both
gcc-4.8.1 and gcc-4.7.3 : the first eight weights[2*i+1] values are wrong.
Happens only when AVX instructions are available (i.e. -O3 -mavx). Does not
happen with O2 or sse2.
The fact that points[] and weights[] assignments are interleaved is important
(no bug otherwise).
Obviously, example has to be run on a system that supports AVX.
/ start
#include iostream
#include vector
using namespace std;
void omb(size_t n, vectordouble points, vectordouble weights)
{
points.resize(n);
weights.resize(n);
for(int i=0;in/2;i++)
{
points[2*i] = .7;
weights[2*i]= 5.;
points[2*i+1] = -.7;
weights[2*i+1]=weights[2*i]; // mis-comiled
}
}
int main()
{
vectordouble p,w;
omb(18, p, w);
for(size_t i=0; i!= p.size(); ++i)
cout i= i p= p[i] w= w[i] endl;
}

[Bug libgomp/58482] gomp4: user defined reduction produce wrong result
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58482 --- Comment #4 from vincenzo Innocente vincenzo.innocente at cern dot ch --- I see.

[Bug libgomp/58482] gomp4: user defined reduction produce wrong result
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58482 --- Comment #5 from Jakub Jelinek jakub at gcc dot gnu.org --- There is no problem with having as many reductions as you need, if they are separate variables; the only case that will prevent vectorization is if you have a struct/class with multiple data members as reduction. I'll see if I can reproduce the ICE on Monday.
[Bug target/58496] New: bug in win64 calling standard
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58496
Bug ID: 58496
Summary: bug in win64 calling standard
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: mikulas at artax dot karlin.mff.cuni.cz
Host: x86_64-pc-cygwin
Target: x86_64-pc-cygwin
Build: x86_64-pc-cygwin
Windows on x86-64 uses a different calling standard than Linux. On Windows x64
ABI, integer arguments are passed in RCX, RDX, R8 and R9. Floating point
arguments are passed in XMM0, XMM1, XMM2, XMM3. For variable-argument
functions,
floating point arguments must be passed in both integer register as well as XMM
register.
If the function was declared with prototype without argument list (such as
int printf()), we don't know if the function has fixed or variable argument
list
and thus we must pass floating point arguments in both integer and XMM
registers.
There comes the bug: this program doesn't print the correct value on Cygwin64
with gcc-4.8.1 because gcc passes the variable 1.2 in XMM1. gcc should pass the
value in both XMM1 and RDX, because the prototype doesn't tell if printf has
variable-argument list or not.
int printf();
int main(void)
{
printf(%f\n, 1.2);
return 0;
}
