Currently you can do stuff like X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=94276b6f934df195ea00000224579f4b9bfa7c5f;p=oota-llvm.git An example testcase for use in the debugger. Currently you can do stuff like stepping, next'ing, finish'ing, stacktraces, source listings, etc. You can't print program variables yet though. Oh, and I lost my nice commented version of funccall.ll :( Test with: llvm-as funccall.ll llvm-db funccall.bc This is not automatically testable yet, and the C front-end doesn't support debug information yet. That said, it's a start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10689 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/test/Debugger/funccall.c b/test/Debugger/funccall.c new file mode 100644 index 00000000000..cc363858ac8 --- /dev/null +++ b/test/Debugger/funccall.c @@ -0,0 +1,14 @@ + +static int q; + +void foo() { + int t = q; + q = t + 1; +} +int main() { + q = 0; + foo(); + q = q - 1; + + return q; +} diff --git a/test/Debugger/funccall.ll b/test/Debugger/funccall.ll new file mode 100644 index 00000000000..096d08b2812 --- /dev/null +++ b/test/Debugger/funccall.ll @@ -0,0 +1,68 @@ + %lldb.compile_unit = type { uint, ushort, ushort, sbyte*, sbyte*, sbyte*, { }* } + %lldb.global = type { uint, %lldb.compile_unit*, sbyte*, { }*, sbyte*, bool } + %lldb.local = type { %lldb.global*, sbyte*, sbyte* } +%llvm.dbg.translation_units = linkonce global { } { } ; <{ }*> [#uses=1] +%llvm.dbg.globals = linkonce global { } { } ; <{ }*> [#uses=1] +%.str_1 = internal constant [11 x sbyte] c"funccall.c\00" ; <[11 x sbyte]*> [#uses=1] +%.str_2 = internal constant [12 x sbyte] c"/home/sabre\00" ; <[12 x sbyte]*> [#uses=1] +%.str_3 = internal constant [14 x sbyte] c"llvmgcc 3.4.x\00" ; <[14 x sbyte]*> [#uses=1] +%d.compile_unit = internal constant %lldb.compile_unit { uint 17, ushort 0, ushort 1, sbyte* getelementptr ([11 x sbyte]* %.str_1, long 0, long 0), sbyte* getelementptr ([12 x sbyte]* %.str_2, long 0, long 0), sbyte* getelementptr ([14 x sbyte]* %.str_3, long 0, long 0), { }* %llvm.dbg.translation_units } ; <%lldb.compile_unit*> [#uses=9] +%.str_5 = internal global [5 x sbyte] c"main\00" ; <[5 x sbyte]*> [#uses=1] +%.str_6 = internal global [4 x sbyte] c"foo\00" ; <[4 x sbyte]*> [#uses=1] +%.str_7 = internal global [2 x sbyte] c"q\00" ; <[2 x sbyte]*> [#uses=1] +%d.main = global %lldb.global { uint 46, %lldb.compile_unit* %d.compile_unit, sbyte* getelementptr ([5 x sbyte]* %.str_5, long 0, long 0), { }* %llvm.dbg.globals, sbyte* null, bool true } ; <%lldb.global*> [#uses=1] +%d.foo = global %lldb.global { uint 46, %lldb.compile_unit* %d.compile_unit, sbyte* getelementptr ([4 x sbyte]* %.str_6, long 0, long 0), { }* %llvm.dbg.globals, sbyte* null, bool true } ; <%lldb.global*> [#uses=1] +%q = internal global int 0 ; [#uses=7] +%d.q = internal global { %lldb.global, int* } { %lldb.global { uint 52, %lldb.compile_unit* %d.compile_unit, sbyte* getelementptr ([2 x sbyte]* %.str_7, long 0, long 0), { }* %llvm.dbg.globals, sbyte* null, bool false }, int* %q } ; <{ %lldb.global, int* }*> [#uses=0] + +implementation ; Functions: + +declare { }* %llvm.dbg.stoppoint({ }*, uint, uint, %lldb.compile_unit*) + +declare { }* %llvm.dbg.func.start(%lldb.global*) + +declare { }* %llvm.dbg.region.start({ }*) + +declare { }* %llvm.dbg.region.end({ }*) + +void %foo() { + %t = alloca int ; [#uses=2] + %.1 = call { }* %llvm.dbg.func.start( %lldb.global* %d.foo ) ; <{ }*> [#uses=1] + %.2 = call { }* %llvm.dbg.stoppoint( { }* %.1, uint 5, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + %tmp.0 = load int* %q ; [#uses=1] + store int %tmp.0, int* %t + %.3 = call { }* %llvm.dbg.stoppoint( { }* %.2, uint 6, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + %tmp.01 = load int* %t ; [#uses=1] + %tmp.1 = add int %tmp.01, 1 ; [#uses=1] + store int %tmp.1, int* %q + %.4 = call { }* %llvm.dbg.stoppoint( { }* %.3, uint 7, uint 1, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + call { }* %llvm.dbg.region.end( { }* %.4 ) ; <{ }*>:0 [#uses=0] + ret void +} + +int %main() { +entry: + %.1 = call { }* %llvm.dbg.func.start( %lldb.global* %d.main ) ; <{ }*> [#uses=1] + %result = alloca int ; [#uses=2] + %.2 = call { }* %llvm.dbg.stoppoint( { }* %.1, uint 9, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + store int 0, int* %q + %.3 = call { }* %llvm.dbg.stoppoint( { }* %.2, uint 10, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + call void %foo( ) + %.4 = call { }* %llvm.dbg.stoppoint( { }* %.3, uint 11, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + %tmp.2 = load int* %q ; [#uses=1] + %tmp.3 = sub int %tmp.2, 1 ; [#uses=1] + store int %tmp.3, int* %q + %.5 = call { }* %llvm.dbg.stoppoint( { }* %.4, uint 13, uint 2, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + %tmp.4 = load int* %q ; [#uses=1] + store int %tmp.4, int* %result + br label %return + +after_ret: ; No predecessors! + br label %return + +return: ; preds = %entry, %after_ret + %tmp.5 = load int* %result ; [#uses=1] + %.6 = call { }* %llvm.dbg.stoppoint( { }* %.5, uint 14, uint 1, %lldb.compile_unit* %d.compile_unit ) ; <{ }*> [#uses=1] + call { }* %llvm.dbg.region.end( { }* %.6 ) ; <{ }*>:0 [#uses=0] + ret int %tmp.5 +}
