2012-11-15Make -ffp-contract a codegen option, rather than a laguage option. This makesLang Hames

2012-08-24[ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a Chad Rosier
CodeGen option to a LangOpt option. In turn, hoist the guard into the parser so that we avoid the new (and fairly unstable) Sema/AST/CodeGen logic.

2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Add a -fuse-init-array option to cc1 and map to the UseInitArray targetRafael Espindola
option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-04This patch adds a new Clang compiler flag "-gline-tables-only".Alexey Samsonov
It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.

2012-03-27Move the emission of strict enum range metadata behind a flag (the sameChandler Carruth
flag as GCC uses: -fstrict-enums). There is a *lot* of code making unwarranted assumptions about the underlying type of enums, and it doesn't seem entirely reasonable to eagerly break all of it. Much more importantly, the current state of affairs is *very* good at optimizing based upon this information, which causes failures that are very distant from the actual enum. Before we push for enabling this by default, I think we need to implement -fcatch-undefined-behavior support for instrumenting and trapping whenever we store or load a value outside of the range. That way we can track down the misbehaving code very quickly. I discussed this with Rafael, and currently the only important cases he is aware of are the bool range-based optimizations which are staying hard enabled. We've not seen any issue with those either, and they are much more important for performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153550 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-14[frontend] Add support for disabling the "inline" keyword using Chad Rosier
-fno-inline-functions. This behaves much like -fno-inline in gcc, but based on a discussion with Daniel it was decided that -fno-inline-functions should subsume -fno-inline. Please speak up if you object. The -fno-inline flag remains ignored. Final part of rdar://10972766 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152754 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-21IRgen: Add a -fuse-register-sized-bitfield-access option, for testing.Daniel Dunbar
- Changes bit-field access policy to try to use (aligned) register sized accesses. The idea here is that by using larger accesses we expose more coalescing potential to the backend when we have situations like adjacent bit-fields in the same structure (which is common), and that the backend should be smart enough to narrow the accesses down when no coalescing is done or when it is shown not to be profitable. -- $ clang -m32 -O3 -S -o - t.c _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movb (%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, (%eax) movb 1(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 1(%eax) movb 2(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 2(%eax) movb 3(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 3(%eax) popl %ebp ret $ clang -m32 -O3 -S -o - t.c -Xclang -fuse-register-sized-bitfield-access _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movl $-2139062144, %ecx ## imm = 0xFFFFFFFF80808080 andl (%eax), %ecx orl $16843009, %ecx ## imm = 0x1010101 movl %ecx, (%eax) popl %ebp ret -- git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133532 91177308-0d34-0410-b5e6-96231b3b80d8
