2012-11-08Set TLSSupported to false on Haiku.Benjamin Kramer
Haiku does not support this (yet). Leaving it set to true leads to configure scripts detecting __thread being available and Clang emitting code for it, resulting in binaries the runtime_loader will refuse to load.

2012-10-16Add pnaclcall convention to Native Client targets.Derek Schuff
Because PNaCl bitcode must be target-independent, it uses some different bitcode representations from other targets (e.g. byval and sret for structures). This means that without additional type information, it cannot meet some native ABI requirements for some targets (e.g. passing structures containing unions by value on x86-64). To allow generation of code which uses the correct native ABIs, we also support triples such as x86_64-nacl, which uses target-dependent IR (as opposed to le32-nacl, which uses byval and sret). To allow interoperation between the two types of code, this patch adds a calling convention attribute to be used in code compiled with the target-dependent triple, which will generate code using the le32-style bitcode. This calling convention does not need to be explicitly supported in the backend because it determines bitcode representation rather than native conventions (the backend just needs to undersand how to handle byval and sret for the Native Client OS). This patch implements __attribute__((pnaclcall)) to generate calls in bitcode according to the le32 bitcode conventions, an attribute which is accepted by any Native Client target, but issues a warning otherwise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166065 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-16Implement GCC's -Wint-to-pointer-cast.David Blaikie
This implementation doesn't warn on anything that GCC doesn't warn on with the exception of templates specializations (GCC doesn't warn, Clang does). The specific skipped cases (boolean, constant expressions, enums) are open for debate/adjustment if anyone wants to demonstrate that GCC is being overly conservative here. The only really obvious false positive I found was in the Clang regression suite's MPI test - apparently MPI uses specific flag values in pointer constants.

2012-10-05Implement -Wshift-op-parentheses for: a << b + cDavid Blaikie
This appears to be consistent with GCC's implementation of the same warning under -Wparentheses. Suppressing a << b + c for cases where 'a' is a user defined type for compatibility with C++ stream IO. Otherwise suggest parentheses around the addition or subtraction subexpression.

2012-09-12Teach -Wuninitialized to recognize __attribute__((analyzer_noreturn))Ted Kremenek
for halting the propagation of uninitialized value tracking along a path. Unlike __attribute__((noreturn)), this attribute (which is used by clients of the static analyzer) can be used to annotate functions that essentially never return, but in rare cares may be allowed to return for (special) debugging purposes. This attribute has been shown in reducing false positives in the static analyzer by pruning false postives, and is equally applicable here.
