80-bit floats support on x86_64 for Valgrind

a project by mfranc

Project Description

Valgrind currently lacks support for 80-bit extended precision floating point arithmetic on x86_64 (long double). The current implementation uses 64-bit arithmetic instead, which means that programs running on x86_64 with "long double" give different results when running under Valgrind and natively. People were asking for support for this since like forever, but to date nobody went on implementing it. It's a project for a year, unless somebody has time to work on it full time, but one has to start somewhere. :-)
