Intel® C++ Compiler

FATAL ERROR - ICC generates dysfunctional code on OSX 32-bit (plus ICC crashes when compiling debug version)

I use ICC on Windows and OSX. On Windows everything is fine. On OSX my project (release version) compiles just fine on 64-bit architecture. But on 32-bit it creates a malfunctioning code that crashes with a call stack containing a single line, saying that it crashed in operator delete(void*, void*). Note, it's the same code (except system services of course) on Windows 32 & 64 and Mac 32 & 64 and ONLY Mac 32 doesn't work. I'm having everything up to date (XCode, OSX, ICC), ICC is called from commandline.

Switching back to vc++: Cannot get rid of /fast option

I've been experimenting with the Intel compiler for the past few weeks, and decided to go back to the VC++ compiler.  I right clicked on the solution and selected "use vc++" compiler.  Tried to build, and got a bunch of warnings about "ignoring unknown option /fast".  I uninstalled the Intel compiler, completely blew away the development directly, got latest from source control, and the warnings are still there.  I searched all of the files in the dev directory (including property sheets and project settings) for the /dev flag.  Nothing. 

VADDSSL instruction?

Dear Intel developers,

I'm using intel 15 on E5-2670 processor. Analyzing my code by using Vtune, in a particolar line when I unpack a m128 type in order to sum in a single floating point each elements like horizontal sum, like this:


_mm_store_ps(denom_arr_tmp, denom_tmp);

 semblance[m_local] += denom_arr_tmp[0]+denom_arr_tmp[1]+denom_arr_tmp[2]+denom_arr_tmp[3];


The assembly generated is:

Initialized Lambda Capture

According to ICC15 should support initialized lambda captures. Yet code like this





*this = make([f, theLocalData = std::move(theLocalData)] {

fails to compile:

error: expected a "]"

1>        *this = make([f, theLocalData = std::move(theLocalData)] {

1>                                      ^


Converting Mixed C/Fortran from MSV2008 to MSV2012, C2065 errors

I'm in process of converting from Microsoft Visual Studio 2008 to MSV2012 for my mixed code, C and FORTRAN application.

The code compiles and executes perfectly for MSV2008 but I receive many, many error messages for the C portion of my code

when I try to compile using MSV2012 wrapper.

The compiler does not like the line:

int _stdcall OPEN_MATLAB(name,ll)

The first couple of error messages are :

1>Source\matlab.c(38): error C2065: 'name' : undeclared identifier

1>Source\matlab.c(38): error C2065: 'll' : undeclared identifier
