2023-01-22Cygwin: mount: allow any valid character in UNC pathsCorinna Vinschen2-3/+15
The current code only allows server and share names to start with ASCII chars [a-zA-Z0-9],, which is not correct. Rather, check for a valid share character. Fixes: 1fd5e000ace55 ("import winsup-2000-02-17 snapshot") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-01-22Cygwin: fsync: Fix EINVAL for block device.Takashi Yano2-1/+7
The commit af8a7c13b516 has a problem that fsync returns EINVAL for block device. This patch treats block devices as a special case. https://cygwin.com/pipermail/cygwin/2023-January/252916.html Fixes: af8a7c13b516 ("Cygwin: fsync: Return EINVAL for special files.")

2023-01-19nvptx: In offloading execution, map '_exit' to 'abort' [GCC PR85463]Thomas Schwinge1-3/+12
This is still not properly resolving <https://gcc.gnu.org/PR85463> '[nvptx] "exit" in offloaded region doesn't terminate process', but is one step into that direction, and allows for simplifying some GCC code.
2023-01-19nvptx: Provide stub 'getpid', 'kill', 'stat'Thomas Schwinge1-0/+17
... as implemented for GCN in 'newlib/libc/sys/amdgcn/*' files, but (for now) still adding to the catch-all 'newlib/libc/machine/nvptx/misc.c' file. This is necessary for the GCC/Fortran I/O system, for example. Co-authored-by: Andrew Stubbs <ams@codesourcery.com>
2023-01-19nvptx: Remove newlib ELIX level 1 restrictionThomas Schwinge2-5/+1
Such a hard-coded ELIX level restriction is only being applied for nvptx newlib -- but we'd actually like higher levels' functions available there, too. (Users continue to be able to override this via newlib 'configure', as for every other newlib target.) This already enables GCC test cases that currently FAIL due to 'unresolved symbol strndup' ('gcc.dg/builtin-dynamic-object-size-0.c'), or 'unresolved symbol mempcpy' ('gcc.dg/torture/pr45636.c'), for example. Co-authored-by: Andrew Stubbs <ams@codesourcery.com>
2023-01-19nvptx: Don't use global constructor for SSP setupThomas Schwinge1-2/+2
Given that nvptx newlib currently restricts itself to ELIX level 1, this is not already a problem. However, in the following we'd like to lift that restriction, and then run into: [...]/newlib/libc/ssp/stack_protector.c: In function ‘__stack_chk_init’: [...]/newlib/libc/ssp/stack_protector.c:31:1: sorry, unimplemented: global constructors not supported on this target 31 | } | ^ GCC patch "nvptx: Support global constructors/destructors via 'collect2'" has been posted, but not yet accepted. Until that is resolved, use the same manual SSP setup as for GCN.
2023-01-19nvptx: Provide stub 'gettimeofday'Thomas Schwinge1-0/+7
Instead of them FAILing due to 'unresolved symbol gettimeofday', this makes PASS a number of GCC 'gfortran.dg' test cases, for example.

2023-01-18Cygwin: open_shared: always bump next_addressCorinna Vinschen1-12/+8
The new loop in open_shared has a subtil performance problem. Next_address is bumped only if mapping at this address failed. Every subsequent call to open_shared has a high probability having to call MapViewOfFileEx twice, because next_address is still set to the address of the last successful mapping. Avoid this by bumping next_address every time. While at it, fix a comment.

2023-01-18amdgcn: Add vectorized math routinesKwok Cheung Yeung96-46/+9990
This implements a set of vectorized math routines to be used by the compiler auto-vectorizer. Versions for vectors with 2 lanes up to 64 lanes (in powers of 2) are provided. These routines are based on the scalar versions of the math routines in libm/common, libm/math and libm/mathfp. They make extensive use of the GCC C vector extensions and GCN-specific builtins in GCC.
2023-01-18Cygwin: drop fixed addresses for standard shared regionsCorinna Vinschen2-51/+18
With the previous commit 9ddd48ee1b8d ("Cygwin: /proc/<PID>/maps: print real shared region addresses"), the real addresses of the standard shared regions (cygwin, user, myself, shared console) are read from the printed process itself. We don't need fixed addresses anymore, so drop the definitions and simplify open_shared. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-01-17Cygwin: /proc/<PID>/maps: print real shared region addressesCorinna Vinschen5-3/+24
So far, the addresses printed for the shared regions of a process were faked. The assumption was that the shared regions are always in the same place in all processes, so we just printed the addresses of the current process. This is no safe bet. The only safe bet is the address of the cygheap. So keep track of the addresses in the cygheap and read the addresses from the cygheap of the observed processes. Add output for the shared console.

2023-01-17Cygwin: disable high-entropy VA for cygcheck and straceCorinna Vinschen1-0/+2
It's not a good idea to enable high-entropy VA for tools loading the Cygwin DLL dynamically. The addresses used by HEVA tend to collide with fixed address areas managed by Cygwin.

2023-01-17Cygwin: open_shared: try harder allocating a shared regionCorinna Vinschen2-11/+53
For fixed regions (cygwin/user/myself/shared console), try fixed address first. Fallback to non-fixed region. Don't even try fixed address if the Cygwin DLL gets dynamically loaded. For non-fixed regions, try to allocate in a loop within the area from SHARED_REGIONS_ADDRESS_LOW to SHARED_REGIONS_ADDRESS_HIGH.

2023-01-17Cygwin: open_shared: don't reuse shared_locations parameter as outputCorinna Vinschen4-29/+31
For ages, open_shared uses the shared_locations parameter as output to indicate if the mapping for a shared region has been created or just opened. Split this into two parameters. Use the shared_locations parameter as input only, return the creation state of the mapping in a bool reference parameter. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

vmstat from proc-ps-4.0.x prints "Unable to create system stat structure" if the /proc/cpuinfo output fails to contain topology info. While Linux always prints topology info if the kernel has been built with CONFIG_SMP, Cygwin only prints topology info if the CPU is known to be multi-core (i. e., the HT feature flag is set). Fix that by printing topology info all the time, even for single-core CPUs.

2023-01-13Cygwin: CI: Run cygserver for testsJon Turney1-3/+13
Note that cygserver must be run using the same cygwin1.DLL as test programs, as they communicate over a named pipe whose name contains the 'installation key' (which is a hash of the cygwin1.dll's path). We run cygserver via 'cmd' to avoid the special code which handles a cygwin parent process starting a cygwin child process, which assumes the same version of cygwin in both.

2023-01-13Cygwin: testsuite: Build testcases using automakeJon Turney7-67/+325
Build all the testcase executables directly using automake, rather than passing the compiler information into DejaGnu to have it build them. (This means you get build avoidance for these executables, so they only get built once, rather than every time you run the test, and makes it much easier to run them in isolatation against the installed Cygwin, which is really nice to have when trying to fix broken tests...) Rename the 'cygrun' subdirectory to 'mingw', and build all the testsuite MinGW executables there. Drop sample-miscompile.c (testing that compile failure is detected is perhaps useful, but not here...)
2023-01-13Cygwin: testsuite: automake doesn't define objdirJon Turney1-1/+1
objdir isn't a predefined output variable in Automake (any more?), so this was just using the absolute path /testsuite as the test's temporary directory. Use builddir instead.
