The x86-record_goto.S assembly source file does not build on 32-bit. This breaks many tests that use this file. Split it into x86_64-record_goto.S and i686-record_goto.S. Luckily, we can use either one with the same test .exp file. It further turned out that most tests do not really need a fixed binary; they should work pretty well with a newly-compiled C program. The one thing that breaks this is the heavy use of "record goto" to navigate inside the recorded execution. Combine step.exp, next,exp, and finish.exp into a single test step.exp and use normal stepping and reverse-stepping commands for navigation. testsuite/ * gdb.btrace/next.exp: Merged into step.exp. * gdb.btrace/finish.exp: Merged into step.exp. * gdb.btrace/nexti.exp: Merged into stepi.exp. * gdb.btrace/step.exp: Use record_goto.c as test file. Avoid using "record goto" and checking the exact replay position. * gdb.btrace/stepi.exp: Choose test file based on target. Do not check for "Recording format" in "info record" output. * gdb.btrace/record_goto.exp: Choose test file based on target. * gdb.btrace/x86-record_goto.S: Renamed into ... * gdb.btrace/x86_64-record_goto.S: ... this. * gdb.btrace/i686-record_goto.S: New. * gdb.btrace/x86-tailcall.S: Renamed into ... * gdb.btrace/x86_64-tailcall.S: ... this. * gdb.btrace/i686-tailcall.S: New. * gdb.btrace/x86-tailcall.c: Renamed into ... * gdb.btrace/tailcall.c: ... this. Split "return ++answer" into two separate statements. Update test. * gdb.btrace/delta.exp: Use record_goto.c as test file. * gdb.btrace/gcore.exp: Use record_goto.c as test file. * gdb.btrace/nohist.exp: Use record_goto.c as test file. * gdb.btrace/tailcall.exp: Choose test file based on target. * gdb.btrace/Makefile.in: Remove next, finish, and nexti.
