* [opaque pointer types] Explicit non-pointer type for call expressionsDavid Blaikie2015-04-161-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | load/store nonsense in the epilog. For example, for: int foo(int X) { int A[100]; return A[X]; } we used to generate: %arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i64 %idxprom ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] store i32 %tmp1, i32* %retval %0 = load i32* %retval ; <i32> [#uses=1] ret i32 %0 } which codegen'd to this code: _foo: ## @foo ## BB#0: ## %entry subq $408, %rsp ## imm = 0x198 movl %edi, 400(%rsp) movl 400(%rsp), %edi movslq %edi, %rax movl (%rsp,%rax,4), %edi movl %edi, 404(%rsp) movl 404(%rsp), %eax addq $408, %rsp ## imm = 0x198 ret Now we generate: %arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i64 %idxprom ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] ret i32 %tmp1 } and: _foo: ## @foo ## BB#0: ## %entry subq $408, %rsp ## imm = 0x198 movl %edi, 404(%rsp) movl 404(%rsp), %edi movslq %edi, %rax movl (%rsp,%rax,4), %eax addq $408, %rsp ## imm = 0x198 ret This actually does matter, cutting out 2000 lines of IR from CGStmt.ll for example. Another interesting effect is that altivec.h functions which are dead now get dce'd by the inliner. Hence all the changes to builtins-ppc-altivec.c to ensure the calls aren't dead. llvm-svn: 106970
* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
* Fix some tests in -Asserts mode.Daniel Dunbar2009-11-111-9/+9
| | | | | | | | | | | | | - FileCheck is a *huuuuge* improvement here. - Still feels like we could use a better tool for this though, either teach llvm-dis to spit out the FileCheck syntax, or provide another tool to turn a .ll into a "matchable" input. - Also on my Christmas list is better FileCheck diagnostics with missing variables or mismatches. llvm-svn: 86800
* Convert a few tests to FileCheck for PR5307.Edward O'Callaghan2009-10-261-1/+14

* Rename clang to clang-cc.Daniel Dunbar2009-03-241-1/+1
| | | | | | Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602
* Change CodeGen of global decls to key off of the name (instead ofDaniel Dunbar2008-08-051-0/+12
having multiple bindings from all the possible decls which conceptually map to the same global). - This eliminates CodeGen depending on the LLVM module for name lookup. - This also eliminates the need for ReplaceMapValuesWith (hurrah). - This handles lookups for FunctionDecls correctly in the presence of aliases, this was previously broken. - WIP: Can still clean up & unify variable and function emission. llvm-svn: 54382
