[SystemZ] Add GHC calling convention This is a special calling convention to be used by the GHC compiler. Author: Stefan Schulze Frielinghaus Differential Revision: https://reviews.llvm.org/D69024
2019-11-04 20:26:38 +08:00
; Check that the GHC calling convention works (s390x)
; In GHC calling convention the only allowed return type is void

Revert "Revert "Reland "[Support] make report_fatal_error `abort` instead of `exit`""" This reverts commit 80a34ae31125aa46dcad47162ba45b152aed968d with fixes. Previously, since bots turning on EXPENSIVE_CHECKS are essentially turning on MachineVerifierPass by default on X86 and the fact that inline-asm-avx-v-constraint-32bit.ll and inline-asm-avx512vl-v-constraint-32bit.ll are not expected to generate functioning machine code, this would go down to `report_fatal_error` in MachineVerifierPass. Here passing `-verify-machineinstrs=0` to make the intent explicit.
