An intuitive web based tool targeted at C++ programmers and
useful for researching,debugging and optimizing code has been
made available. GCC Explorer is the brainchild of Matt Godbolt
who explains his reasons for creating it in his blog: One of the
things I spend a fair amount of time doing at work is compiling
my C/C++ code and looking at the disassembly output. Call me
old-fashioned, but I think sometimes the only way to really grok
your code is to see what the processor will actually execute.
Particularly with some of the newer features of C++11 — lambdas,
move constructors, threading primitives etc — it’s nice to be
able to see how your elegant code becomes beautiful (and maybe
even fairly optimal) machine code. Having crafted aweb-based
tool for exploring the output of the compiler under small tweaks
of the code, compiler version and compiler flags, Matt was given
permission by his company to open source it. The latest release
of GCC Explorer has added more compilers GCC4.7, AVR, ARM, MSP
to those avail
