Bus error gcc compiler for any for ( x in array ) inside Objective-C++ template

Hi, I've encountered a bus error using Apple's gcc in Xcode 3.1, 3.2 compiling the following code or any containing for( x in y ) is used inside a template in Objective-C++. template class OODictionary { void boom() { NSArray *keys = nil; for ( NSString

RE: Turning off unrolling to certain loops

Hello, I faced a similar issue a while ago. I filed a bug report (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36712) In the end, I implemented a simple tree-level unrolling pass in our port which uses all the existing infrastructure. It works quite well for our purpose, but I hesitated to submit

I'm porting gcc , and use its autovectorization. How can I know wether a standard name support a vector mode ? Thanks!

Storing 16bit values in upper part of 32bit registers

Hi, I am working with an architecture where the 32bit registers (rN) are divided into high (rNh) and low (rNl) 16bit sub registers that can in principle be individually accessed by the instructions in the IS. However the IS is designed so that it is beneficial to to store 16bit values in the high

Re: Storing 16bit values in upper part of 32bit registers

Hi Marcus, Though I am novice in gcc , I think I can answer your question. As far as I know, your load instruction will take care of this issue. You need to restrict your load instruction so that it will place your return value of function in lower r

Re: Turning off unrolling to certain loops

You are entirely correct, I hadn't thought that through enough. So I backtracked and have just merged what Bingfeng Mei has done with your code and have now a corrected version of the loop unrolling. What I did was directly modified tree_unroll_loop to handle the case of a perfect unroll or not i

RE: Turning off unrolling to certain loops

Jc, How did you implement #pragma unroll? I checked other compilers. The pragma should govern the next immediate loop. It took me a while to find a not-so-elegant way to do that. I also implemented #pragma ivdep. These information are supposed to be passed through both tree and RTL levels and suv

Question on C++-0x constexpr

I was toying around with constexpr in the standard library and tripped on this: // /bin/bin/g++ -std=c++0x -c template_constexpr.cpp template class A { static constexpr int foo() { retur

Re: Turning off unrolling to certain loops

I implemented it like this: - I modified c_parser_for_statement to include a pragma tree node in the loop with the unrolling request as an argument - Then during my pass to handle unrolling, I parse the loop to find the pragma. - I retrieve the unrolling factor and use a merge of Zdenek'
