From 5fdae9d3be45ce17e22b5f7a742cae3dfe687516 Mon Sep 17 00:00:00 2001 From: Jeff Hostetler Date: Tue, 21 May 2019 12:33:59 -0700 Subject: [PATCH] trace2: fix tracing when NO_PTHREADS is defined Teach trace2 TLS code to not rely on pthread_getspecific() when NO_PTHREADS is defined. Instead, always assume the context data of the main thread.
