From f630777f5ba60277ce44c6905c0fa72d0d34c6e0 Mon Sep 17 00:00:00 2001 From: Zachary Turner Date: Fri, 17 Nov 2017 00:41:18 +0000 Subject: Re-revert "Refactor debuginfo-tests" This is still broken because it causes certain tests to be run twice with slightly different configurations, which is wrong in some cases. You can observe this by running: ninja -nv check-all | grep debuginfo-tests And seeing that it passes clang/test and clang/test/debuginfo-tests to lit, which causes it to run debuginfo-tests twice. The fix is going to involve either: a) figuring out that we're running in this "deprecated" configuration, and then deleting the clang/test/debuginfo-tests path, which should cause it to behave identically to before, or: b) make lit smart enough that it doesn't descend into a sub-suite if that sub-suite already has a lit.cfg file. --- debuginfo-tests/dbg-arg.c | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 debuginfo-tests/dbg-arg.c (limited to 'debuginfo-tests/dbg-arg.c') diff --git a/debuginfo-tests/dbg-arg.c b/debuginfo-tests/dbg-arg.c new file mode 100644 index 00000000000..a65dc910b8b --- /dev/null +++ b/debuginfo-tests/dbg-arg.c @@ -0,0 +1,46 @@ +// This test case checks debug info during register moves for an argument. +// RUN: %clang %target_itanium_abi_host_triple -m64 -mllvm -fast-isel=false %s -c -o %t.o -g +// RUN: %clang %target_itanium_abi_host_triple -m64 %t.o -o %t.out +// RUN: %test_debuginfo %s %t.out +// +// DEBUGGER: break 26 +// DEBUGGER: r +// DEBUGGER: print mutex +// CHECK: ={{.* 0x[0-9A-Fa-f]+}} +// +// Radar 8412415 + +struct _mtx +{ + long unsigned int ptr; + int waiters; + struct { + int tag; + int pad; + } mtxi; +}; + + +int foobar(struct _mtx *mutex) { + int r = 1; + int l = 0; + int j = 0; + do { + if (mutex->waiters) { + r = 2; + } + j = bar(r, l); + ++l; + } while (l < j); + return r + j; +} + +int bar(int i, int j) { + return i + j; +} + +int main() { + struct _mtx m; + m.waiters = 0; + return foobar(&m); +} -- cgit v1.2.3
