rdar://8560647 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120650 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-02Enhance the init generation logic to emit a memset followed by a few stores whenChris Lattner
a global is larger than 32 bytes and has fewer than 6 non-zero values in the initializer. Previously we'd turn something like this: char test8(int X) { char str[10000] = "abc"; into a 10K global variable which we then memcpy'd from. Now we generate: %str = alloca [10000 x i8], align 16 %tmp = getelementptr inbounds [10000 x i8]* %str, i64 0, i64 0 call void @llvm.memset.p0i8.i64(i8* %tmp, i8 0, i64 10000, i32 16, i1 false) store i8 97, i8* %tmp, align 16 %0 = getelementptr [10000 x i8]* %str, i64 0, i64 1 store i8 98, i8* %0, align 1 %1 = getelementptr [10000 x i8]* %str, i64 0, i64 2 store i8 99, i8* %1, align 2 Which is much smaller in space and also likely faster.

2010-11-30A CGRecordLayout object persists. Since its contained types mayJohn McCall

2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119730 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Calculate the value kind of an expression when it's created andJohn McCall
store it on the expression node. Also store an "object kind", which distinguishes ordinary "addressed" l-values (like variable references and pointer dereferences) and bitfield, @property, and vector-component l-values. Currently we're not using these for much, but I aim to switch pretty much everything calculating l-valueness over to them. For now they shouldn't necessarily be trusted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119685 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17When forming the !srcloc mdnode for an inline asm, add the SourceLocations Chris Lattner
of all the lines of the inline asm. With the refactoring and enhancement of the backend, we can now reports errors on the correct source line when an asm contains multiple lines of text. For something like this: void foo() { asm("push %rax\n" ".code32\n"); } we used to get this: (note that the line 4 in t.c isn't helpful) t.c:4:7: error: warning: ignoring directive for now asm("push %rax\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ now we get: t.c:5:8: error: warning: ignoring directive for now ".code32\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ Note that we're pointing to line 5 properly now. This implements rdar://7839391 - inline asm errors should point to the right line in the asm and makes the error message in PR8595 much less confusing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119489 91177308-0d34-0410-b5e6-96231b3b80d8
