I am planning to do some work with SMT solvers and GCC.

I have recently seen several discussions on Twitter where people have been surprised/annoyed by what the compilers do to their branchless code.

GCC per default enables one optimization for x86_64 that can change the result of floating-point operations: -ffp-contract=fast.1 This allows the compiler to do floating-point expression contraction such as combining multiplication and addition instructio…

My previous blog post said that computations producing Inf, NaN, or -0.0 in programs compiled with -ffinite-math-only and -fno-signed-zeros might cause the program to behave in strange ways, such as not evaluating either the true or false part of an if-st…
