why 6Gb RAM not enough to compile a 14Mb source [MELT]?

Hello All, my MELT branch http://gcc.gnu.org/wiki/MiddleEndLispTranslator has a big source file in it warm-basilys-0.c. It is "self" generated, about 14Mbytes & almost 280KLOC (in rev136334). It ends with a big initialization routine of 100KLOC which mostly fills a 5000 member structure (each

Re: No warning for unreachable code

I just discovered a behaviour in gcc-4, which I don't understand: code unsigned int x; if (x < 0) do_something(); compiled with -Wall doesn't produce a warning, and the call to do_something() is silently dropped, whereas if x is of type unsigned char, I get as

Why g++ does not emit any information for a local variable in a template class member function?

Hi, I have the following code. I try to print the variable temp in the constructor of A. But gdb can not do that. The error message is shown blow the C++ code. According to the people from gdb mailing list, it is because that the compiler (g++) does not generate information for such variable in

How to reserve an Elf e_machine value

I am working on a compiler kit for an in-house processor that uses Elf as object file format. Since this compiler will be released to external customers, I need to reserve an 'official' e_machine value for this processor. Somehow I am unable to find out how to reserve such a value. How should I

[tuples] Memory savings in gimple.h

Hi! I think 2/3 operand GIMPLE_ASSIGN is the most widely used gimple type, and 128 bytes + 16/24 bytes in separate allocation for it is a lot (though, we'd need a separate extra_order_size_table for such GIMPLE_ASSIGNs if we decrease it a little bit). The low hanging fruit on 64-bit arches is mov

Cross compiling gcc-4.3: wrong library path

Hello, I'm trying to cross compile gcc-4.3 for emdebian.org and i have got some compilers for some arches but i'm struggling with some other arches (like powerpc, mips(el), sparc and s390). Those architectures have separated ABIs for (n)32, 64. The problem i have is that ../lib64 and ../lib32 are
