## This test checks how we handle the --bb-addr-map option.
## Check 64-bit:
# RUN: yaml2obj --docnum=1 %s -DBITS=64 -DADDR=0x999999999 -o %t1.x64.o
# RUN: llvm-readobj %t1.x64.o --bb-addr-map 2>&1 | FileCheck %s -DADDR=0x999999999 -DFILE=%t1.x64.o --check-prefix=CHECK
# RUN: llvm-readelf %t1.x64.o --bb-addr-map | FileCheck %s --check-prefix=GNU
## Check 64-bit:
# RUN: yaml2obj --docnum=1 %s -DBITS=64 -DADDR=0x999999999 -o %t1.v1.x64.o
# RUN: llvm-readobj %t1.v1.x64.o --bb-addr-map 2>&1 | FileCheck %s -DADDR=0x999999999 -DFILE=%t1.v1.x64.o --check-prefix=CHECK
## Check 32-bit:
# RUN: yaml2obj --docnum=1 %s -DBITS=32 -o %t1.x32.o
# RUN: llvm-readobj %t1.x32.o --bb-addr-map 2>&1 | FileCheck -DADDR=0x11111 %s -DFILE=%t1.x32.o --check-prefix=CHECK
# RUN: llvm-readelf %t1.x32.o --bb-addr-map | FileCheck %s --check-prefix=GNU
## Check that a malformed section can be handled.
# RUN: yaml2obj --docnum=1 %s -DBITS=32 -DSIZE=6 -o %t2.o
# RUN: llvm-readobj %t2.o --bb-addr-map 2>&1 | FileCheck %s -DOFFSET=0x00000006 -DFILE=%t2.o --check-prefix=TRUNCATED

## Check that using the SHT_LLVM_BB_ADDR_MAP_V0 section type generates the same
## result as using the SHT_LLVM_BB_ADDR_MAP section type with Version=0.
## The Version field is required even for SHT_LLVM_BB_ADDR_MAP_V0 but it
## should not impact the result. This unideal behavior will be gone once
## SHT_LLVM_BB_ADDR_MAP_V0 is deprecated.
