2026-01-11tools/nolibc: Add a simple test for writing to a FILE and reading it backDaniel Palmer-0/+53
Add a test that exercises create->write->seek->read to check that using the stream functions (fwrite() etc) is not totally broken. The only edge cases this is testing for are: - Reading the file after writing but without rewinding reads nothing. - Trying to read more items than the file contains returns the count of fully read items.

2026-01-11selftests/nolibc: also test libc-test through regular selftest frameworkThomas Weißschuh-1/+5
Hook up libc-test to the regular selftest build to make sure nolibc-test.c stays compatible with a normal libc. As the pattern rule from lib.mk does not handle compiling a target from a differently named source file, add an explicit rule definition.

2026-01-11selftests/nolibc: try to read from stdin in readv_zero testThomas Weißschuh-1/+1
When stdout is redirected to a file this test fails. This happens when running through the kselftest runner since commit d9e6269e3303 ("selftests/run_kselftest.sh: exit with error if tests fail"). For consistency with other tests that read from a file descriptor, switch to stdin over stdout. The tests are still brittle against a redirected stdin, but at least they are now consistently so.

Since LLVM commit 39e30508a7f6 ("[Driver][Sparc] Default to -mcpu=v9 for 32-bit Linux/sparc64 (#109278)"), clang defaults to -mcpu=v9 for 32-bit SPARC builds. -mcpu=v9 generates instructions which are not recognized by qemu-sparc and qemu-system-sparc.

2026-01-06selftests/nolibc: drop NOLIBC_SYSROOT=0 logicThomas Weißschuh-6/+0
This logic was added in commit 850fad7de827 ("selftests/nolibc: allow test -include /path/to/nolibc.h") to allow the testing of -include /path/to/nolibc.h. As it requires as special variable to activate, this code is nearly never used. Furthermore it complicates the logic a bit. Since commit a6a054c8ad32 ("tools/nolibc: add target to check header usability") and commit 443c6467fcd6 ("selftests/nolibc: always run nolibc header check") the usability of -include /path/to/nolibc.h is always checked anyways, making NOLIBC_SYSROOT=0 pointless.

2025-07-04tools/nolibc: add support for SuperHThomas Weißschuh-1/+9
Add support for SuperH/"sh" to nolibc. Only sh4 is tested for now. The startup code is special: __nolibc_entrypoint_epilogue() calls __builtin_unreachable() which emits a call to abort(). To make this work a function prologue is generated to set up a GOT pointer which corrupts "sp". __builtin_unreachable() is necessary for __attribute__((noreturn)). Also depending on compiler flags (for example -fPIC) even more prologue is generated. Work around this by defining a nested function in asm.

2025-06-10selftests/nolibc: make stackprotector probing more robustThomas Weißschuh-1/+4
nolibc only supports symbol-based stackprotectors, based on the global variable __stack_chk_guard. Support for this differs between architectures and toolchains. Some use the symbol mode by default, some require a flag to enable it and some don't support it at all. Before the nolibc test Makefile required the availability of "-mstack-protector-guard=global" to enable stackprotectors. While this flag makes sure that the correct mode is available it doesn't work where the correct mode is the only supported one and therefore the flag is not implemented. Switch to a more dynamic probing mechanism. This correctly enables stack protectors for mips, loongarch and m68k.
