Frits van Bommel	5ecdf1a70a	Eliminate comparisons between GC allocations and constants. This removes some ... `assert(this !is null)`s when member functions get inlined. Also tweak pass order a bit.	2009-06-20 14:28:59 +02:00
Frits van Bommel	d1f582583b	Turn new _d_array_slice_copy runtime call into memcpy when the slice lengths are ... equal and alias analysis says it's safe.	2009-05-10 04:18:14 +02:00
Frits van Bommel	634d623b34	Some tweaks to -simplify-drtcalls.	2009-05-09 02:34:27 +02:00
Frits van Bommel	34955bcbf9	Remove calls to some runtime functions if their results are unused	2009-05-02 11:58:50 +02:00
Frits van Bommel	0df1e34eb2	Implement first D-specific optimization pass: -simplify-drtcalls. ... It uses the machinery of the standard -simplify-libcalls pass, but optimizes calls to the D runtime instead of calls to C libraries. At the moment, these optimizations are implemented by this pass: - Avoid the runtime call for `arr.length = newlen` if it can determine that the new length isn't longer than the old one. - Ditto for `cast(T[]) arr` if it will clearly always succeed. (e.g. if the length of the original array is zero, or if the old element size is a multiple of the new element size)	2009-04-28 21:58:06 +02:00
