Re: [Tinycc-devel] manually inlining functions

[Yakov]

I have recently read a paper about a Linear Scan Register Allocator[1], they claim it gives you 95% performance or Graph Coloring Register Allocator in basically no time, and requires no SSA.

Calls are fairly cheap, on modern architectures.  The performance impact
of an inliner would be fairly marginal for tcc, compared with, say, a
register allocator.
