Bill Wendling0a794a4b2013-11-20 10:13:37 +0000[diff] [blame]39What's New in Clang 3.5?
Sean Silvafe251442012-12-23 01:19:35 +0000[diff] [blame]40========================
41
42Some of the major new features and improvements to Clang are listed
43here. Generic improvements to Clang as a whole or to its underlying
44infrastructure are described first, followed by language-specific
45sections with improvements to Clang's support for those languages.

47Major New Features
48------------------

50Improvements to Clang's diagnostics
51^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
52
53Clang's diagnostics are constantly being improved to catch more issues,
54explain them more clearly, and provide more accurate source information
Bill Wendling0a794a4b2013-11-20 10:13:37 +0000[diff] [blame]55about them. The improvements since the 3.4 release include:

64C Language Changes in Clang
65---------------------------
66
Renato Golin1588cda2013-12-11 09:35:10 +0000[diff] [blame]67The integrated assembler is now turned on by default on ARM (and Thumb),
68so the use of the option `-integrated-as` is now redundant on those
69architectures. This is an important move to both *eat our own dog food*
70and to ease cross-compilation tremendously.
71
72We are aware of the problems that this may cause for code bases that
73rely on specific GNU syntax or extensions, and we're working towards
74getting them all fixed. Please, report bugs or feature requests if
75you find anything. In the meantime, use `-no-integrated-as` to revert
76back the call to GNU assembler.

108this section should help get you past the largest hurdles of upgrading.
