From 76675de15cfc0912cb1b3520ec59768d96d501d2 Mon Sep 17 00:00:00 2001 From: Erich Keane Date: Thu, 5 Jul 2018 17:22:13 +0000 Subject: [clang-cl, PCH] Implement support for MS-style PCH through headers Implement support for MS-style PCH through headers. This enables support for /Yc and /Yu where the through header is either on the command line or included in the source. It replaces the current support the requires the header also be specified with /FI. This change adds a -cc1 option -pch-through-header that is used to either start or stop compilation during PCH create or use. When creating a PCH, the compilation ends after compilation of the through header. When using a PCH, tokens are skipped until after the through header is seen.
