From 1ee73216f4ccd2f3b6eb818feb165b3cf5a1944c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 22 Sep 2016 15:17:10 -0700 Subject: log: Add locking to large logging blocks Reuse the existing locking provided by stdio to keep in_asm, cpu, op, op_opt, op_ind, and out_asm as contiguous blocks. While it isn't possible to interleave e.g. in_asm or op_opt logs because of the TB lock protecting all code generation, it is possible to interleave cpu logs, or to interleave a cpu dump with an out_asm dump. For mingw32, we appear to have no viable solution for this. The locking functions are not properly exported from the system runtime library.
