From 288bc7b5d17511d1791899e4b2e3bf3489eb06dd Mon Sep 17 00:00:00 2001 From: Hongyu Wang Date: Wed, 8 Mar 2023 11:29:46 +0800 Subject: libgomp: Fix default value of GOMP_SPINCOUNT [PR 109062] When OMP_WAIT_POLICY is not specified, current implementation will cause icv flag GOMP_ICV_WAIT_POLICY unset, so global variable wait_policy will remain its uninitialized value. Initialize it to -1 to make GOMP_SPINCOUNT behavior consistent with its description. libgomp/ChangeLog: PR libgomp/109062 * env.c (wait_policy): Initialize to -1. (initialize_icvs): Initialize icvs->wait_policy to -1. * testsuite/libgomp.c-c++-common/pr109062.c: New test. --- libgomp/env.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libgomp/env.c') diff --git a/libgomp/env.c b/libgomp/env.c index c41c1f8..e7a035b 100644 --- a/libgomp/env.c +++ b/libgomp/env.c @@ -124,7 +124,7 @@ int goacc_default_dims[GOMP_DIM_MAX]; #ifndef LIBGOMP_OFFLOADED_ONLY -static int wait_policy; +static int wait_policy = -1; static unsigned long stacksize = GOMP_DEFAULT_STACKSIZE; static void @@ -1981,7 +1981,7 @@ initialize_icvs (struct gomp_initial_icvs *icvs) icvs->bind_var = gomp_default_icv_values.bind_var; icvs->nteams_var = gomp_default_icv_values.nteams_var; icvs->teams_thread_limit_var = gomp_default_icv_values.teams_thread_limit_var; - icvs->wait_policy = 0; + icvs->wait_policy = -1; } /* Helper function for initialize_env to add a device specific ICV value -- cgit v1.1
