In this 19# case, the call is made from sub1 (provided by libdso1) and we are 20# calling sub2 (provided by libdso2). 21# 22# Note that, while this is not the main purpose of this testcase, it 23# also happens to exercise an issue with displaced stepping on amd64 24# when libdso1 is mapped at an address greater than 0xffffffff. 25 26if { [skip_shlib_tests] } { 27 return 0 28} 29 30standard_testfile 31 32set output_dir [standard_output_file {}] 33 34set libdso2 $testfile-dso2 35set srcfile_libdso2 $srcdir/$subdir/$libdso2.c 36set binfile_libdso2 [standard_output_file $libdso2.so] 37 38set libdso1 $testfile-dso1 39set srcfile_libdso1 $srcdir/$subdir/$libdso1.c 40set binfile_libdso1 [standard_output_file $libdso1.so] 41 42if { [gdb_compile_shlib $srcfile_libdso2 $binfile_libdso2 \ 43 [list debug additional_flags=-fPIC]] != "" } { 44 untested "failed to compile shared library 2" 45 return -1 46} 47 48if { [gdb_compile_shlib $srcfile_libdso1 $binfile_libdso1 \ 49 [list debug additional_flags=-fPIC]] != "" } { 50 untested "failed to compile shared library 1" 51 return -1 52} 53 54if { [gdb_compile $srcdir/$subdir/$srcfile $binfile executable \ 55 [list debug shlib=$binfile_libdso2 shlib=$binfile_libdso1]] != "" } { 56 return -1 57} 58 59clean_restart $binfile 60gdb_load_shlib $binfile_libdso2 61gdb_load_shlib $binfile_libdso1 62 63if { ![runto_main] } { 64 return -1 65} 66 67set bp_location [gdb_get_line_number "STOP HERE" [file tail $srcfile_libdso1]] 68gdb_breakpoint ${libdso1}.c:${bp_location} 69 70gdb_continue_to_breakpoint "at call to sub2" \ 71 ".*sub2 ().*" 72 73gdb_test "next" \ 74 ".*return 5;.*" \ 75 "next over call to sub2" 76
