Subject: [gcc r12-6996] gcc: define _REENTRANT for OpenRISC when -pthread is passed
Date: Wed,  2 Feb 2022 11:03:21 +0000 (GMT)	[thread overview]
Message-ID: <20220202110321.E35423858C2C@sourceware.org> (raw)

commit r12-6996-gcac2f69cdad434ad5cb60f5fe931d45cd82ef476
Author: Bernd Kuhls <bernd.kuhls@t-online.de>

    gcc: define _REENTRANT for OpenRISC when -pthread is passed
    
    The detection of pthread support fails on OpenRISC unless _REENTRANT
    is defined. Added the CPP_SPEC definition to correct this.

            PR target/94372
            * config/or1k/linux.h (CPP_SPEC): Define.
