From 0877ba7cbf275fdcd45e3c33768d258fc75feb5b Mon Sep 17 00:00:00 2001 From: Philip Date: Sat, 2 May 2015 12:58:37 +0000 Subject: tccpp.c: parse flag to accept stray \ This adds a PARSE_FLAG_ACCEPT_STRAYS parse flag to accept stray backslashes in the source code, and uses it for pure preprocessing. For absolutely correct behaviour of # stringification, we need to use this flag when parsing macro definitions and in macro arguments, as well; this patch does not yet do so. The test case for that is something like #define STRINGIFY2(x) #x #define STRINGIFY(x) STRINGIFY2(x) STRINGIFY(\n) which should produce "\n", not a parse error or "\\n".
