--- Comment #10 from Richard Biener ---
btw, -fno-var-tracking also greatly improves compile-time (but does nothing to
memory use). Compiling with -O1 reduces memory use to 300MB even when
var-tracking is enabled. So an option might be to

If we are using an arch without BMI2, we can use single MUL instruction
instead. Here is the description of MUL reg64/mem64.
Multiplies a 64-bit register or memory operand by the contents

My host compiler (x86_64, older trunk) uses "just" 800MB. 3.5GB looks like a
runaway? What uarch is your i586 compiler targeting?

--- Comment #4 from accelerator0099 at gmail dot com ---
Well, I hope gcc will just generate mulx instruction on arch with BMI2. Let's
look at the AMD64 Architecture Programmer’s Manual Volume 3:
Computes the unsigned product of the specified
