Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Running llc on the following test uses up all memory on my machine. Probably
codegen should detect and error out on huge stack frames.
target triple = "x86_64-unknown-linux-gnu"
%struct.frame_overflow__bitmap_t = type { [9223372036854775807 x i8] }
define void @frame_overflow() {
entry:
%memtmp = alloca %struct.frame_overflow__bitmap_t, align 8
ret void
}
