James Greenhalgh <jgreenhalgh at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jgreenhalgh at gcc dot gnu.org, | |wdijkstr at arm dot com --- Comment #3 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> --- I see about 250 new failures when testing with -mcmodel=tiny after r243346. These are of the same form as the failure you report: FAIL: gfortran.dg/alloc_comp_assign_4.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (test for excess errors) /tmp/ccxfODDL.s: Assembler messages: /tmp/ccxfODDL.s:30: Error: invalid addressing mode at operand 3 -- `ldp x24,x25,.LC2' I haven't seen this for other values of mcmodel in my testing. I wonder how -mcmodel=tiny made it in to your bootstrap flags? This patch probably should be reverted for now given the number of failures.
