--- Comment #25 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:f1b3e3853329b58fb2e50c17487df2ecbc4a5608 commit r12-7486-gf1b3e3853329b58fb2e50c17487df2ecbc4a5608 Author: Iain Sandoe <i...@sandoe.co.uk> Date: Wed Feb 23 13:53:44 2022 +0000 LRA, rs6000, Darwin: Revise lo_sum use for forced constants [PR104117]. Follow up discussion to the initial patch for this PR identified that it is preferable to avoid the LRA change, and arrange for the target to reject the hi and lo_sum selections when presented with an invalid address. We split the Darwin high/low selectors into two: 1. One that handles non-PIC addresses (kernel mode, mdynamic-no-pic). 2. One that handles PIC addresses and rejects SYMBOL_REFs unless they are suitably wrapped in the MACHOPIC_OFFSET unspec. The second case is handled by providing a new predicate (macho_pic_address) that checks the requirements.
