The clauses are either implicit (added by gdb_test_multiple) or explicit (passed via the gdb_test_multiple parameter user_code). However, there are a few implicit clauses which are inserted before the explicit ones, making sure those take precedence. Add an -early pattern flag for a gdb_test_multiple user_code clause to specify that the clause needs to be inserted before any implicit clause. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-12 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (gdb_test_multiple): Handle -early pattern flag. ------------------------------------------------------------ [gdb/testsuite] Mark watchthreads-reorder.exp FAIL as KFAIL [ https://sourceware.org/ml/gdb-patches/2019-09/msg00221.html ] When running gdb.threads/watchthreads-reorder.exp in parallel with: ... $ n=$(grep -c processor /proc/cpuinfo); n=$((($n + 1) / 2)); stress -c $n ... there's a reasonable change to trigger an internal gdb error: ... $ for n in $(seq 1 10); do ./test.sh; done 2>&1 \ | grep "expected passes" \ | sort \ | uniq -c 1 # of expected passes 14 2 # of expected passes 15 1 # of expected passes 16 6 # of expected passes 17 ... which look like this in gdb.sum: ... FAIL: gdb.threads/watchthreads-reorder.exp: reorder1: continue to breakpoint: \ break-at-exit (GDB internal error) ... This FAIL is filed as PR gdb/24995 and fixed on master by commit c29705b71a "Fix internal error and improve 'set debug infrun 1'/target wait kind trace". Mark this as KFAIL for the 8.3 branch. It's trivial to do this by adding a setup_kfail: ... + setup_kfail gdb/24995 "*-*-*" gdb_continue_to_breakpoint "break-at-exit" ".*break-at-exit.*" ... but we'll get a fair amount of KPASSES: ... KPASS: gdb.threads/watchthreads-reorder.exp: reorder0: \ continue to breakpoint: break-at-exit (PRMS gdb/24995) KPASS: gdb.threads/watchthreads-reorder.exp: reorder1: \ continue to breakpoint: break-at-exit (PRMS gdb/24995) ... Instead, do this more precise by only KFAILing in case the internal error is detected. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-12 Tom de Vries <tdevries@suse.de> * gdb.threads/watchthreads-reorder.exp: Add PR gdb/24995 KFAIL. ------------------------------------------------------------ [gdb/testsuite] Allow some tests in gdb.base/restore.exp to be unsupported [ Backport of master commit 77d036789aa. ] We currently run into: ... 248 n = callee1 (n + l5); (gdb) PASS: gdb.base/restore.exp: caller5 calls callee1; return callee now print l1 $51 = <optimized out> (gdb) FAIL: gdb.base/restore.exp: caller5 calls callee1; return restored l1 \ to 32492 ... The problem is that we try to access the value of l1 in function caller5, but variable l1 has no DW_AT_location attribute. Since l1 is declared using the register keyword, it's valid for gcc to emit no DW_AT_location at -O0. Change the FAIL into an UNSUPPORTED. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-22 Tom de Vries <tdevries@suse.de> * gdb.base/restore.exp: Allow register variables to be optimized out at -O0. ------------------------------------------------------------ [gdb/testsuite] Allow some tests in gdb.base/store.exp to be unsupported [ Backport of master commit 25e5c20918a. ] The test-case gdb.base/store.exp fails with gcc 7.4.0: ... nr of unexpected failures 27 ... The first FAIL: ... 110 l = add_float (l, r); (gdb) PASS: gdb.base/store.exp: continue to wack_float print l $21 = <optimized out> FAIL: gdb.base/store.exp: var float l; print old l, expecting -1 ... relates to this bit in the test-case (compiled at -O0): ... 106 float 107 wack_float (register float u, register float v) 108 { 109 register float l = u, r = v; 110 l = add_float (l, r); 111 return l + r; 112 } ... and it expects to be able to read and modify variable l before executing line 110, but it already fails to read the value, because l has no DW_AT_location attribute in the debug info. Variable l is declared with the register keyword, and GCC implements the register keyword at -O0 like so: ... the compiler allocates distinct stack memory for all variables that do not have the register storage-class specifier; if register is specified, the variable may have a shorter lifespan than the code would indicate and may never be placed in memory. ... The fact that l has no DW_AT_location attribute, matches with the documented "variable may have a shorter lifespan that code would indicate", (though it is the most extreme case of it) so the gcc behaviour is valid. We can of course improve gcc to generate better debuginfo (filed gcc PR91611), but this not a wrong-debug problem. [ The test-case passes with gcc 4.2.1, but for the failing test discussed above, it passes simply because it doesn't store l in a register. ] With the debug info missing for l, reading and setting l is unsupported, so fix the FAIL by marking the test UNSUPPORTED instead. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-12 Tom de Vries <tdevries@suse.de> * gdb.base/store.exp: Allow register variables to be optimized out at -O0. ------------------------------------------------------------ [gdb/testsuite] Require gnatmake 8 for gdb.ada/rename_subscript_param.exp [ Backport of master commit d1b70248bde. ] When running gdb.ada/rename_subscript_param.exp with gnatmake 7.4.1, we get: ...

The commit last touching the test-case (afcfda091e) states: ... The test still fails with old compilers that do not properly generate debug info for this renaming: ... Fix this by requiring at least gnatmake 8 for the test-case.

FAIL: gdb.base/gcore.exp: corefile restored all registers ... The problem is that there's a difference in the mxcsr register value before and after the gcore command: ... - mxcsr 0x0 [ ] + mxcsr 0x400440 [ DAZ OM ] ... This can be traced back to amd64_linux_nat_target::fetch_registers, where xstateregs is partially initialized by the ptrace call: ... char xstateregs[X86_XSTATE_MAX_SIZE]; struct iovec iov; amd64_collect_xsave (regcache, -1, xstateregs, 0); iov.iov_base = xstateregs; iov.iov_len = sizeof (xstateregs); if (ptrace (PTRACE_GETREGSET, tid, (unsigned int) NT_X86_XSTATE, (long) &iov) < 0) perror_with_name (_("Couldn't get extended state status")); amd64_supply_xsave (regcache, -1, xstateregs); ... after which amd64_supply_xsave is called. The amd64_supply_xsave call is supposed to only use initialized parts of xstateregs, but due to a kernel bug on intel skylake (fixed from 4.14 onwards by commit 0852b374173b "x86/fpu: Add FPU state copying quirk to handle XRSTOR failure on Intel Skylake CPUs") it can happen that the mxcsr part of xstateregs is not initialized, while amd64_supply_xsave expects it to be initialized, which explains the FAIL mentioned above. Fix the undetermined behaviour by initializing xstateregs before calling ptrace, which makes sure we get a 0x0 for mxcsr when this kernel bug occurs, and which also happens to fix the FAIL. Furthermore, add an xfail for this FAIL which triggers the same kernel bug: ... FAIL: gdb.arch/amd64-init-x87-values.exp: check_setting_mxcsr_before_enable: \ check new value of MXCSR is still in place ... Both FAILs pass when using a 5.3 kernel instead on the system mentioned above.
