+
+; The patch that includes this test case, is addressing the following issue:
+;
+; When functions are inlined, instructions without debug information
+; are attributed with the call site's DebugLoc. After inlining, inlined static
+; allocas are moved to the caller's entry block, adjacent to the caller's original
+; static alloca instructions. By retaining the call site's DebugLoc, these instructions
+; may cause instructions that are subsequently inserted at the entry block to pick
+; up the same DebugLoc.
+;
+; In the offending case stack protection inserts an instruction at the caller's
+; entry block, which inadvertently picks up the inlined call's DebugLoc, because
+; the entry block's first instruction is the recently moved inlined alloca instruction.
+;
+; The stack protection instruction then becomes part of the function prologue, with the
+; result that the line number that is associated with the stack protection instruction
+; is deemed to be the end of the function prologue. Since this line number is the
+; call site's line number, setting a breakpoint at the function in the debugger
+; will make the user stop at the line of the inlined call.
+
+; Note that without the stack protection instruction this effect would not occur
+; because the allocas all get collapsed into a single instruction that reserves
+; stack space and have no further influence on the prologue's line number information.
+
+
+; The selected solution is to not attribute static allocas with the call site's
+; DebugLoc.
+
+; At some point in the future, it may be desirable to describe the inlining
+; in the alloca instructions, but then the code that handles prologues must
+; be able to handle this correctly, including the late insertion of instructions
+; into it.
+
+; In this context it is also important to distingush between functions
+; with the "nodebug" attribute and those without it. Alloca instructions from
+; nodebug functions should continue to have no DebugLoc, whereas those from
+; non-nodebug functions (i.e. functions with debug information) may want to
+; have their DebugLocs augmented with inlining information.
+
+
+; Make sure that after inlining the call to foo() the alloca instructions for
+; arr.i and sum.i do not retain debug information.

-
-; The patch that includes this test case, is addressing the following issue:
-;
-; When functions are inlined, instructions without debug information
-; are attributed with the call site's DebugLoc. After inlining, inlined static
-; allocas are moved to the caller's entry block, adjacent to the caller's original
-; static alloca instructions. By retaining the call site's DebugLoc, these instructions
-; may cause instructions that are subsequently inserted at the entry block to pick
-; up the same DebugLoc.
-;
-; In the offending case stack protection inserts an instruction at the caller's
-; entry block, which inadvertently picks up the inlined call's DebugLoc, because
-; the entry block's first instruction is the recently moved inlined alloca instruction.
-;
-; The stack protection instruction then becomes part of the function prologue, with the
-; result that the line number that is associated with the stack protection instruction
-; is deemed to be the end of the function prologue. Since this line number is the
-; call site's line number, setting a breakpoint at the function in the debugger
-; will make the user stop at the line of the inlined call.
-
-; Note that without the stack protection instruction this effect would not occur
-; because the allocas all get collapsed into a single instruction that reserves
-; stack space and have no further influence on the prologue's line number information.
-
-
-; The selected solution is to not attribute static allocas with the call site's
-; DebugLoc.
-
-; At some point in the future, it may be desirable to describe the inlining
-; in the alloca instructions, but then the code that handles prologues must
-; be able to handle this correctly, including the late insertion of instructions
-; into it.
-
-; In this context it is also important to distingush between functions
-; with the "nodebug" attribute and those without it. Alloca instructions from
-; nodebug functions should continue to have no DebugLoc, whereas those from
-; non-nodebug functions (i.e. functions with debug information) may want to
-; have their DebugLocs augmented with inlining information.
-
-
-; Make sure that after inlining the call to foo() the alloca instructions for
-; arr.i and sum.i do not retain debug information.
