Add indents to AST dumping and removed parenthesis from AST nodes. Indents were given the color blue when outputting with color. AST dumping now looks like this: Node |-Node | `-Node `-Node `-Node Compared to the previous: (Node (Node (Node)) (Node (Node))) llvm-svn: 174022

// CHECK-ATTR-NEXT: ConstantExpr
[clang] Rework how and when APValues are dumped Currently APValues are dumped as a single string. This becomes quickly completely unreadable since APValue is a tree-like structure. Even a simple example is not pretty: struct S { int arr[4]; float f; }; constexpr S s = { .arr = {1,2}, .f = 3.1415f }; // Struct fields: Array: Int: 1, Int: 2, 2 x Int: 0, Float: 3.141500e+00 With this patch this becomes: -Struct |-field: Array size=4 | |-elements: Int 1, Int 2 | `-filler: 2 x Int 0 `-field: Float 3.141500e+00 Additionally APValues are currently only dumped as part of visiting a ConstantExpr. This patch also dump the value of the initializer of constexpr variable declarations: constexpr int foo(int a, int b) { return a + b - 42; } constexpr int a = 1, b = 2; constexpr int c = foo(a, b) > 0 ? foo(a, b) : foo(b, a); // VarDecl 0x62100008aec8 <col:3, col:57> col:17 c 'const int' constexpr cinit // |-value: Int -39 // `-ConditionalOperator 0x62100008b4d0 <col:21, col:57> 'int' // <snip> Do the above by moving the dump functions to TextNodeDumper which already has the machinery to display trees. The cases APValue::LValue, APValue::MemberPointer and APValue::AddrLabelDiff are left as they were before (unimplemented). We try to display multiple elements on the same line if they are considered to be "simple". This is to avoid wasting large amounts of vertical space in an example like: constexpr int arr[8] = {0,1,2,3,4,5,6,7}; // VarDecl 0x62100008bb78 <col:3, col:42> col:17 arr 'int const[8]' constexpr cinit // |-value: Array size=8 // | |-elements: Int 0, Int 1, Int 2, Int 3 // | `-elements: Int 4, Int 5, Int 6, Int 7 Differential Revision: https://reviews.llvm.org/D83183 Reviewed By: aaron.ballman
