This test causes several timeouts for Clang, taking too long time to finish. The reason is, for an infinite loop of the form while(1); /* suppose this is line 30. */ Clang generates code that looks like 0x00000000004004d4 <+4>: jmp 0x4004d9 <loop+9> 0x00000000004004d9 <+9>: jmp 0x4004d9 <loop+9> So, the real loop is the instruction at address 0x4004d9. But a breakpoint that's defined at the loop line (assume line 30 in this case) is inserted at address 0x4004d4. (gdb) break 30 Breakpoint 1 at 0x4004d4: file test.c, line 30. Therefore, continuing a thread that was spinning on the loop does not hit the breakpoint. The bug is reported at https://bugs.llvm.org/show_bug.cgi?id=49614 Tweak the infinite loop to spin on a variable to avoid this bug. The test is unrelated to the bug. gdb/testsuite/ChangeLog: 2021-03-29 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.mi/user-selected-context-sync.exp: Spin on a variable in the infinite loop to avoid a Clang bug. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
