From 58df1affedc0d68eda16b87984a31dea217ff930 Mon Sep 17 00:00:00 2001 From: Mike Rice Date: Tue, 11 Sep 2018 17:10:44 +0000 Subject: [clang-cl, PCH] Support for /Yc and /Yu without filename and #pragma hdrstop With clang-cl, when the user specifies /Yc or /Yu without a filename the compiler uses a #pragma hdrstop in the main source file to determine the end of the PCH. If a header is specified with /Yc or /Yu #pragma hdrstop has no effect. The optional #pragma hdrstop filename argument is not yet supported.
