[OpenMP] Use the OpenMPIRBuilder for `omp parallel` This allows to use the OpenMPIRBuilder for parallel regions. Code was extracted from D61953 and adapted to work with the new version (D70109). All but one feature should be supported. An update of this patch will provide test coverage and privatization other than shared.

[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Change memcpy/memove/memset to have dest and source alignment attributes (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964

Initial support for Win64 SEH IR emission The lowering looks a lot like normal EH lowering, with the exception that the exceptions are caught by executing filter expression code instead of matching typeinfo globals. The filter expressions are outlined into functions which are used in landingpad clauses where typeinfo would normally go. Major aspects that still need work: - Non-call exceptions in __try bodies won't work yet. The plan is to outline the __try block in the frontend to keep things simple. - Filter expressions cannot use local variables until capturing is implemented. - __finally blocks will not run after exceptions. Fixing this requires work in the LLVM SEH preparation pass. The IR lowering looks like this: // C code: bool safe_div(int n, int d, int *r) { __try { *r = normal_div(n, d); } __except(_exception_code() == EXCEPTION_INT_DIVIDE_BY_ZERO) { return false; } return true; } ; LLVM IR: define i32 @filter(i8* %e, i8* %fp) { %ehptrs = bitcast i8* %e to i32** %ehrec = load i32** %ehptrs %code = load i32* %ehrec %matches = icmp eq i32 %code, i32 u0xC0000094 %matches.i32 = zext i1 %matches to i32 ret i32 %matches.i32 } define i1 zeroext @safe_div(i32 %n, i32 %d, i32* %r) { %rr = invoke i32 @normal_div(i32 %n, i32 %d) to label %normal unwind to label %lpad normal: store i32 %rr, i32* %r ret i1 1 lpad: %ehvals = landingpad {i8*, i32} personality i32 (...)* @__C_specific_handler catch i8* bitcast (i32 (i8*, i8*)* @filter to i8*) %ehptr = extractvalue {i8*, i32} %ehvals, i32 0 %sel = extractvalue {i8*, i32} %ehvals, i32 1 %filter_sel = call i32 @llvm.eh.seh.typeid.for(i8* bitcast (i32 (i8*, i8*)* @filter to i8*)) %matches = icmp eq i32 %sel, %filter_sel br i1 %matches, label %eh.except, label %eh.resume eh.except: ret i1 false eh.resume: resume } Reviewers: rjmccall, rsmith, majnemer Differential Revision: http://reviews.llvm.org/D5607 llvm-svn: 226760

Change memcpy/memove/memset to have dest and source alignment attributes (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964

[OPENMP] Initial codegen for '#pragma omp parallel' llvm-svn: 208077
2014-05-06 18:08:46 +08:00
[OpenMP] Use the OpenMPIRBuilder for `omp parallel` This allows to use the OpenMPIRBuilder for parallel regions. Code was extracted from D61953 and adapted to work with the new version (D70109). All but one feature should be supported. An update of this patch will provide test coverage and privatization other than shared.
