http://d.puremagic.com/issues/show_bug.cgi?id=11345 Summary: Optimize array literal to static array assignment to not allocate on GC heap Product: D Version: D2 Platform: All OS/Version: All Status: NEW Keywords: performance Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: verylonglogin.reg gmail.com 00:16:45 MSD --- This has already been introduced when fixing Issue 2356 in dmd pull 1883 [1] but was reverted because of Issue 11238 in dmd pull 2682 [2]: --- void main() { int[2] m = [4, 6]; // optimized (Issue 2356) m = [m[1], m[0]]; // swap, currently calls `_d_arrayliteralTX` assert(m == [6, 4]); } --- Instead of calling `_d_arrayliteralTX` it should be rewritten to create a temporary static array if needed.
