Attached please find the Assembler output created by gcc -save-temps,
both the original version and the one with limited inlining.

The former requires a 1360 bytes stack frame, the latter 1232 bytes.
E.g. xycz_initial_double() is not inlined into ecc_point_mult(),
together with all its recursive baggage, so the latter version
contains two branch instructions to that function which the former
(original) version does not contain.

At the beginning of the function, it looks like the same register values
are stored to multiple locations on the stack. I assume that's what you
mean by awful code generation? This odd behavior seems more subdued in
the version with limited inlining.

I will respin and I will also take Nathan's suggestion into account.

Thanks,

Lukas
