From c24f559435f7c47da9e46a559026a604cfb3307b Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 18 Sep 2014 15:19:12 +0400 Subject: [PATCH] gcc: add new fix for the ARC 2014.08 gcc version This commit adds a new patch to the ARC 2014.08 gcc specific version, that redefines PTRDIFF_TYPE from "long int" to "int". The change of SIZE_TYPE from "long unsigned int" to "unsigned int" http://git.buildroot.net/buildroot/commit/?id=0f236c1fef669192c8f5cc8ef26e93da91438dc2 introduced a regression due to the existing PTRDIFF_TYPE. Now to fix regression the patch converts PTRDIFF_TYPE to simple "int". The fix is taken from current development branch of GCC for ARC and will be a part of the next release of ARC tools, so at that point patch should be dropped. https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/commit/846e92167aa4f486259c9ff44bb4e6cce6097fa4 [Thomas: tweak commit log.] Signed-off-by: Alexey Brodkin Cc: Anton Kolesov Cc: Thomas Petazzoni Cc: Peter Korsgaard Signed-off-by: Thomas Petazzoni --- .../arc-2014.08/300-ptrdiff_type_int.patch | 26 +++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 package/gcc/arc-2014.08/300-ptrdiff_type_int.patch diff --git a/package/gcc/arc-2014.08/300-ptrdiff_type_int.patch b/package/gcc/arc-2014.08/300-ptrdiff_type_int.patch new file mode 100644 index 0000000000..6ee765be33 --- /dev/null +++ b/package/gcc/arc-2014.08/300-ptrdiff_type_int.patch @@ -0,0 +1,26 @@ +Redefine PTRDIFF_TYPE + +Change of SIZE_TYPE from "long unsigned int" to "unsigned int" introduced +regression due to existing PTRDIFF_TYPE. + +Now to fix regression convert PTRDIFF_TYPE to simple "int". + +Fix is taken from current development branch of GCC for ARC and will be a +part of the next release of ARC tools, so at that point patch should be dropped. + +https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/commit/846e92167aa4f486259c9ff44bb4e6cce6097fa4 + +Signed-off-by: Claudiu Zissulescu +--- + +--- a/gcc/config/arc/arc.h ++++ b/gcc/config/arc/arc.h +@@ -488,7 +488,7 @@ if (GET_MODE_CLASS (MODE) == MODE_INT \ + #define DEFAULT_SIGNED_CHAR 0 + + #define SIZE_TYPE "unsigned int" +-#define PTRDIFF_TYPE "long int" ++#define PTRDIFF_TYPE "int" + #define WCHAR_TYPE "int" + #define WCHAR_TYPE_SIZE 32 + -- 2.30.2
