Consider the following source file `asm_pic.d`: align(16) static immutable short[8] A = [ 1, 1, 1, 1, 3, 3, 3, 3 ]; void main() { asm { pmullw XMM0, A; } } LDC 1.0.0-b1 thinks it's compatible with PIC code. ```bash $ ldc2 asm_pic.d # ok $ ldc2 -relocation-model=pic asm_pic.d # ok ``` DMD disallows to load the constant in PIC code. $ dmd asm_pic.d # ok $ dmd -fPIC asm_pic.d # fail asm_pic.d(7): Error: cannot directly load global variable 'A' with PIC code

Well I don't have that issue anymore.
