[WinEH] Remove NewMSEH and enable its behavior by default Testing has shown that it is at least as reliable as the old landingpad pattern matching code. llvm-svn: 249647

[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).

Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

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

[OPENMP][DEBUG] Generate second function with correct arg types. Currently, if the some of the parameters are captured by value, this argument is converted to uintptr_t type and thus we loosing the debug info about real type of the argument (captured variable): ``` void @.outlined_function.(uintptr %par); ... %a = alloca i32 %a.casted = alloca uintptr %cast = bitcast uintptr* %a.casted to i32* %a.val = load i32, i32 *%a store i32 %a.val, i32 *%cast %a.casted.val = load uintptr, uintptr* %a.casted call void @.outlined_function.(uintptr %a.casted.val) ... ``` To resolve this problem, in debug mode a speciall external wrapper function is generated, that calls the outlined function with the correct parameters types: ``` void @.wrapper.(uintptr %par) { %a = alloca i32 %cast = bitcast i32* %a to uintptr* store uintptr %par, uintptr *%cast %a.val = load i32, i32* %a call void @.outlined_function.(i32 %a) ret void } void @.outlined_function.(i32 %par); ... %a = alloca i32 %a.casted = alloca uintptr %cast = bitcast uintptr* %a.casted to i32* %a.val = load i32, i32 *%a store i32 %a.val, i32 *%cast %a.casted.val = load uintptr, uintptr* %a.casted call void @.wrapper.(uintptr %a.casted.val) ... ``` llvm-svn: 306697

Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record.

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
