2014-01-28Clang plugin to warn about implicit conversion of literals to boolStephan Bergmann1-0/+140
...which warns about apparent errors like n == KIND_FOO || KIND_BAR that should have read n == KIND_FOO || n == KIND_BAR It also warns about trivial (mis-)uses of 0/1 and sal_False/True like while (1) { ... } instead of while (true) { ... } which it can automatically rewrite. It does not warn if the relevant code is inside a macro in a .h (i.e., C) include file, nor when a string literal is used in the assert macro like assert(!"this cannot happen"); Change-Id: If8c305a25e5da15e78f6139b5b0c0e868f06d4f3

2014-01-22implicitboolconversion: also warn about mixing bool/sal_Bool in == etc.Stephan Bergmann1-13/+16
...as MSVC would warn about those anyway (at least about cases that do not compare against literal sal_True/sal_False, but warning even about those helped clean up lots of redundant if (foo == true) instead of just if (foo) etc. across the code base).

2014-01-17Clang plugin that flags implicit conversions from boolStephan Bergmann1-0/+480
...as they are often enough errors, like a typo in brace placement in if (foo == (FOO || bar == BAR) && baz) or a literal true passed as an argument to a function that rather expects an integer bit mask, etc. The plugin is smart enough to detect interaction with logically boolean return/parameter types of C functions that use [unsigned] int instead, and knows the relevant boolean typedefs (sal_Bool, gboolean, etc.).

2014-01-10Clang plugin to re-write SvStream operator<< to non-overloaded methodsNoel Grandin1-0/+181
Use a clang rewriter to rewrite SvStream::operator<< to methods like WriteUInt32. Note that the rewriter is not perfect, and hand-tweaking the output is necessary.

2013-07-15compiler plugin warning about unwanted silent pointer-to-bool conversionsLuboš Luňák1-0/+163
C/C++ silently converts pointers to booleans, which is presumably seen as a good idea by lazy people, but it can occassionally silently break code in strange ways, most notably by selecting a bool overload when no matching overload for the pointer exists (OUStringBuffer::append() can break like that, e.g. in ba37e4062f538db7e51d6a64ba544eeddbc567cf, other cases are 8e3bf1598fa95ac8d099e45ae4252e7654a6f590 or 28e4c0250e67a344b4d6088bdca2e680a4bffad0). So far the plugin checks only conversions in function call arguments, there's disabled code that could check more places, but I'm not aware so far of any place where anything actually broke because of that, and it'd require fixups to be explicit in some places (e.g. 'bool b = returns_pointer();' would require '!= NULL' added), so for it'll be only the simple various and it can be made more strict if wanted.
