[RISCV] Change func to funct in RISCVInstrInfoXqci.td. NFC (#119669)
[llvm-project.git] / llvm / test / tools / llvm-symbolizer / only-empty-ranges.s
blob8f00c458b7620413a29df7fdef6123efeb3f42f3
1 # REQUIRES: x86-registered-target
2 # RUN: llvm-mc -filetype=obj -triple=x86_64-pc-linux %s -o %t.o
3 # RUN: llvm-symbolizer 0x0 0x2 0x3 0x4 --obj=%t.o | FileCheck %s
4 # This test makes sure we don't attempt to access out of the line table boundaries
5 # if the last range is empty.
6 # Produced from the following program:
7 # int func(int a) {
8 # return 1 + a;
9 # }
10 # compiled with clang -O3 -g -S
11 # Edited by adding a redundant, empty last range.
12 # The line table (llvm-dwarfdump --debug-line) looks like:
13 #
14 # Address Line Column File ISA Discriminator OpIndex Flags
15 # ------------------ ------ ------ ------ --- ------------- ------- -------------
16 # 0x0000000000000000 1 0 1 0 0 0 is_stmt
17 # 0x0000000000000000 2 12 1 0 0 0 is_stmt prologue_end
18 # 0x0000000000000003 2 3 1 0 0 0
19 # 0x0000000000000003 3 3 1 0 0 0
20 # 0x0000000000000004 3 3 1 0 0 0 end_sequence
21 #
22 # 0x0 should pick the second line in the table - line 2, col 12
23 # CHECK: func
24 # CHECK: /scratch/a.cpp:2:12
25 # 0x2 does not exist in the table, so we should pick the line with a
26 # lower address that describes the range - in this case, the second line.
27 # CHECK: func
28 # CHECK: /scratch/a.cpp:2:12
29 # 0x3 also has a sequence of empty ranges, so we should pick the first range after
30 # skipping the empty ones.
31 # This also verifies we don't attempt to access outside boundaries.
32 # CHECK: func
33 # CHECK: /scratch/a.cpp:3:3
34 # CHECK: ??
35 # CHECK: ??:0:0
