[LLVMdev] IR extension proposal: bitset constants
...l %continue, label %trap In the LTO case, such intrinsic calls would be lowered by the bitset lowering pass into the appropriate range/bit set check code, which might look like this: (pseudocode for 64-bit platform) if %vtable & 7 != 0 || %vtable < global_start_addr(_ZBS1A) || %vtable > global_end_addr(_ZBS1A) { %p = 0 } else { %p = bitset(_ZBS1A)[(%vtable - global_start_addr(_ZBS1A)) >> 3] } In the non-LTO case, we would generate similar code, but with appropriate relocations so that the required constants (global start/end address, bitset address, mask, shift amount) would receive ap...
