* Cygwin: Testsuite Makefile cleanupJon Turney2020-11-181-13/+2
| | | | | | Drop unused variables CC_FOR_TARGET, GCC_INCLUDE, ALL_CFLAGS Stop exporting CC, CFLAGS Drop unused, empty targets force, dll_ofiles, all_target
* Cygwin: Fix 'make check' in utilsJon Turney2020-11-183-10/+12
| | | | | | | | | | | | | | This has a test of the path translation code used in various utilities (mount, cygpath, strace). MOUNT_BINARY is replaced with the absence of MOUNT_TEXT since 26e0b37e. The issys member of mnt_t struct was removed in b677a99b. > $ make check [...] > total tests: 63 > pass : 63 (100.0%) > fail : 0 (0.0%)
* Cygwin: Drop duplicate C++ flags used to build utilsJon Turney2020-11-181-1/+1
| | | | | | '-fno-exceptions -fno-rtti' are already present in the compile command COMPILE.cc set by Makefile.common, so we don't need to add them to CXXFLAGS as well.
* Cygwin: Use grep in text mode to look for version stringsJon Turney2020-11-181-1/+1
| | | | | | | Invoke grep in text mode when looking for version strings inside the cygwin DLL, so it outputs something more informative than: Binary file ../cygwin/cygwin0.dll matches

* malloc/nano-malloc: correctly check for out-of-bounds allocation reqsCorinna Vinschen2020-11-173-2/+31
| | | | | | | | | | | | The overflow check in mEMALIGn erroneously checks for INT_MAX, albeit the input parameter is size_t. Fix this to check for __SIZE_MAX__ instead. Also, it misses to check the req against adding the alignment before calling mALLOc. While at it, add out-of-bounds checks to pvALLOc, nano_memalign, nano_valloc, and Cygwin's (unused) dlpvalloc.

| | | | | | | Don't call cstrdup on NULL pointers. This fixes a crash that was observed when cloning an fhandler whose path_conv member had freed its strings.

* Cygwin: fhandler_fifo: reduce sizeKen Brown2020-11-092-9/+14
| | | | | | | | | | Replace the 'WCHAR pipe_name_buf[48]' class member by 'PWCHAR pipe_name_buf', and allocate space for the latter as needed. Change the default constructor to accommodate this change, and add a destructor that frees the allocated space. Also change get_pipe_name and clone to accommodate this change.
* Cygwin: Ensure temporary directory used by tests existsJon Turney2020-11-083-4/+15
| | | | | | | | | | | | | | | By default, libltp tests will create temporary files in a subdirectory of /tmp, which will (nowadays) be located relative to the test DLL (by assuming that it is in /bin). This will evaluate to the directory $target_builddir/winsup/tmp, which doesn't exist. The location used for these temporary files can be explicitly controlled by setting the TDIRECTORY env var. Arrange to set that env var to the /cygdrive path of a tmp subdirectory of the build directory. Unfortunately, libltp doesn't clean the temporary directory if TDIRECTORY is set, and some tests assume they are started in a clean directory, so we need to do that in tcl.
* Cygwin: Set PATH for tests to pick up cygwin0.dllJon Turney2020-11-081-0/+2
| | | | | | Set the PATH so that tests can pick up cygwin0.dll. Looks like this was dropped by accident in 2e488e95 ("Don't rely on in-build tools"), so restore it as it was prior to 9d89f634.
* Cygwin: Check exit code of a test, rather than stdoutJon Turney2020-11-081-7/+13
| | | | | In winsup.exp, don't consider a command failed if it produced any output (e.g. if the compiler produced warnings). Instead check the exit code.
* Cygwin: Use absolute path to libltp includesJon Turney2020-11-081-1/+1
| | | | | Use an absolute path to libltp includes, to allow for the fact that we'll be compiling tests in a subdirectory.
* Cygiwn: Detect and use MinGW compilers for testsuite wrappersJon Turney2020-11-084-4/+255
| | | | | | | Drop MINGW_FE, which I can't find any trace of, and instead detect and use MinGW compilers. This requires adding AC_CANONICAL_TARGET, to set $target_cpu.
* Cygwin: Define target_builddir autoconf and Makefile variablesJon Turney2020-11-083-0/+10
| | | | | | | | | This is now required as cygwin_build is defined in terms of target_builddir. (Note that in other subdirectories, the autoconf variable target_builddir is AC_SUBST-ed as a side-effect of using a macro from winsup/acinclude.m4, which is perhaps less than ideal)
* Cygwin: Move adding libltp to VPATH after Makefile.commonJon Turney2020-11-081-2/+2
| | | | Move adding libltp to the VPATH after Makefile.common, which sets VPATH.
* Cygwin: Avoid 'Makefile.in seems to ignore the --datarootdir setting' warningJon Turney2020-11-081-0/+1

* Cygwin: Always configure in testsuite subdirectoryJon Turney2020-11-083-18/+4
| | | | | Doing this properly using AC_CONFIG_SUBDIRS is necessary to get the correct paths in flags given to the compiler specified in CC/CXX.

* Cygwin: Drop passing '-c' compiler flag into gentls_offsetsJon Turney2020-11-021-1/+1
| | | | | That script appends a '-E', since we only use $(CC) to preprocess, and thus adding '-c' is having no effect.

* Cygwin: Drop autoconf variable all_hostJon Turney2020-11-025-54/+2
| | | | | | | | The autoconf variable all_host is used to make building of the stub library used by the testsuite conditional on not cross-compiling. Make it unconditional, so we will notice if it's broken when cross-compiling.
* Cygwin: Remove autoconf variable DLL_NAMEJon Turney2020-11-023-9/+2
| | | | | Remove autoconf variable DLL_NAME, which has a constant value which is only used in one place.
* Cygwin: Drop AC_SUBST(build_exeext)Jon Turney2020-11-021-2/+0
| | | | | The autoconf variable build_exeext isn't defined, and (since the doc subdirectory doesn't build any executables) it's value isn't used.

* Cygwin: Restore setting CC and CXX Makefile variablesJon Turney2020-10-283-0/+10
| | | | | | | | | | | b55e3f19 was a bit too aggressive in dropping, rather than just un-exporting these Makefile variables. We need to set these to the configured host compiler if we are cross-compiling, otherwise they default to the build compiler. Also export CC to the mkvers.sh script (which requires it since 4eca5e6a). It's unclear why we can't just cause windres to use the build 'cpp' as the pre-processor there.
* libc/sys/rtems/include/machine/_types.h: Define daddr_t to be 64 bits for RTEMSJoel Sherrill2020-10-281-0/+3

* Cygwin: fix return value of sqrtl on negative infinityKen Brown2020-10-272-2/+8
| | | | | | | | | | | | The return value is now -NaN. This fixes a bug in the mingw-w64 code that was imported into Cygwin. The fix is consistent with Posix and Linux. It is also consistent with the current mingw-w64 code, with one exception: The mingw-w64 code sets errno to EDOM if the input is -NaN, but this appears to differ from Posix and Linux.

* Cygwin: pty: Disable ResizePseudoConsole() if stdout is redirected.Takashi Yano via Cygwin-patches2020-10-273-2/+8
| | | | | | | | - Calling ResizePseudoConsole() generates some escape sequences. Due to this behaviour, if the output of non-cygwin app is piped to less, screen is sometimes distorted when the screen is resized. With this patch, ResizePseudoConsole() is not called if stdout is redirected.

* Define RB_SET_PARENT to do all assignmentsdougm2020-10-261-30/+28
| | | | | | | | | | | | | | | to rb parent pointers. Define RB_SWAP_CHILD to replace the child of a parent with its twin, and use it in 4 places. Use RB_SET in rb_link_node to remove the only linuxkpi reference to color, and then drop color- and parent-related definitions that are defined and used only in rbtree.h. This is intended to be entirely cosmetic, with no impact on program behavior, and leave RB_PARENT and RB_SET_PARENT as the only ways to read and write rb parent pointers.

In the case when both of the children are red, the current implementation uses two rotations where only one is necessary.
