2023-06-23compiler, libgo: support bootstrapping gc compilerIan Lance Taylor3-8/+4
In the Go 1.21 release the package internal/profile imports internal/lazyregexp. That works when bootstrapping with Go 1.17, because that compiler has internal/lazyregep and permits importing it. We also have internal/lazyregexp in libgo, but since it is not installed it is not available for importing. This CL adds internal/lazyregexp to the list of internal packages that are installed for bootstrapping. The Go 1.21, and earlier, releases have a couple of functions in the internal/abi package that are always fully intrinsified. The gofrontend recognizes and intrinsifies those functions as well. However, the gofrontend was also building function descriptors for references to the functions without calling them, which failed because there was nothing to refer to. That is OK for the gc compiler, which guarantees that the functions are only called, not referenced. This CL arranges to not generate function descriptors for these functions.

2023-06-20runtime: use a C function to call mmapIan Lance Taylor5-15/+38
The final argument to mmap, of type off_t, varies. In CL 445375 we changed it to always use the C off_t type, but that broke 32-bit big-endian Linux systems. On those systems, using the C off_t type requires calling the mmap64 function. In C this is automatically handled by the <sys/mman.h> file. In Go, we would have to change the magic //extern comment to call mmap64 when appropriate. Rather than try to get that right, we instead go through a C function that uses C implicit type conversions to pick the right type.

2023-06-16libgo/testsuite: add benchmarks and examples to listIan Lance Taylor2-4/+15
In CL 384695 I simplified the code that built lists of benchmarks, examples, and fuzz tests, and managed to break it. This CL corrects the code to once again make the benchmarks available, and to run the examples with output and the fuzz targets. Doing this revealed a test failure in internal/fuzz on 32-bit x86: a signalling NaN is turned into a quiet NaN on the 387 floating-point stack that GCC uses by default. This CL skips the test.

2022-09-27runtime: portable access to sigev_notify_thread_idIan Lance Taylor2-1/+29
Previously, libgo relied on the _sigev_un implementation-specific field in struct sigevent, which is only available on glibc. This patch uses the sigev_notify_thread_id macro instead which is mandated by timer_create(2). In theory, this should work with any libc implementation for Linux. Unfortunately, there is an open glibc bug as glibc does not define this macro. For this reason, a glibc-specific workaround is required. Other libcs (such as musl) define the macro and don't require the workaround. See https://sourceware.org/bugzilla/show_bug.cgi?id=27417 This makes libgo compatible with musl libc.
