Signed vs unsigned lower halves of powerpc fixups are now handled by having two assembler directives, ha16() and has16(), for the upper half; has16() applies the sign adjustment. .powerpcfixup is now gone, as we generate the relocation in ha*() instead. Add special logic to the linker for undoing and redoing the sign adjustment when reading/writing fixups. Tests still pass. 2017-01-15 10:51:37 +00:00			`#include <stdbool.h>`

Turns out Apple's hi16/ha16 exactly match my ha16/has16, so renamed accordingly. (Memo to self: read the docs before doing the work.) 2017-01-15 10:59:33 +00:00			`extern quad emit_hi(struct expr_t* expr, bool is_signed);`
