2011-04-21Wire up the -ftest-coverage and -fprofile-arcs flags to .gcno file emission (atNick Lewycky
compile time) and .gcda emission (at runtime). --coverage enables both. This does not yet add the profile_rt library to the link step if -fprofile-arcs is enabled when linking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129956 91177308-0d34-0410-b5e6-96231b3b80d8

double data[20000000] = {0}; we would blow out the memory by creating 20M Exprs to fill out the initializer. To fix this, if the initializer list initializes an array with more elements than there are initializers in the list, have InitListExpr store a single 'ArrayFiller' expression that specifies an expression to be used for value initialization of the rest of the elements.

2011-04-17Fix a miscompilation I introduced in r129652, thanks for Eli for tracking Chris Lattner
it down. we effectively were compile the testcase into: void test14(int x) { switch (x) { case 11: break; case 42: test14(97); // fallthrough default: test14(42); break; which is not the same thing at all.

turns out that a field or base needs to be laid out in the tail padding of the base, CGRecordLayoutBuilder::ResizeLastBaseFieldIfNecessary will convert it to an array of i8.

there is no reason to align them higher. - This roughly matches llvm-gcc's r126913. - It is an open question whether or not we should do this for cstring's in general (code size vs optimization potential), for now we just match llvm-gcc until someone wants to run some experiments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129410 91177308-0d34-0410-b5e6-96231b3b80d8
