Subject: [OpenRISC] [PATCH] gcc: define _REENTRANT for OpenRISC when -pthread is passed
Date: Mon, 31 Jan 2022 22:38:13 +0900 [thread overview]
Message-ID: <20220131133813.1142801-1-shorne@gmail.com> (raw)
From: Bernd Kuhls <bernd.kuhls@t-online.de>
The detection of pthread support fails on OpenRISC unless _REENTRANT
is defined. Added the CPP_SPEC definition to correct this.
gcc/ChangeLog:
PR target/94372
* config/or1k/linux.h (CPP_SPEC): Define.
Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de>

This was brought up on the buildroot list and somehow I missed it. Sending it
now. I plan to commit soon.
