Sjoerd Meijer 068d715728 [SelectionDAG] Codesize: don't expand SHIFT to SHIFT_PARTS ... And instead just generate a libcall. My motivating example on ARM was a simple: shl i64 %A, %B for which the code bloat is quite significant. For other targets that also accept __int128/i128 such as AArch64 and X86, it is also beneficial for these cases to generate a libcall when optimising for minsize. On these 64-bit targets, the 64-bits shifts are of course unaffected because the SHIFT/SHIFT_PARTS lowering operation action is not set to custom/expand.
