2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe2-2/+17
Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.

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.

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.
