- Subject: GCC and Floating-Point
Hello.
I'm writing an extensive article about floating-point programming on
Linux, including a focus on GCC's compilers. This is an outgrowth of
many debates about topics like -ffast-math and -mfpmath=sse|387, and I
hope it will prove enlightening for myself and others.
Among the subjects covered: accuracy, precision, data organization, code
speed, threading issues, and a bit about interval arithmetic and
significant digits.
Naturally, due to hardware availability, I'll be focusing on x86 and
x86_64 systems.
I'd appreciate comments, ideas, and suggestions from the folk on this
mailing list.
Thank you.
..Scott
