2022-10-27runtime: use _libgo_off_t_type when calling C mmapIan Lance Taylor1-2/+4
The last argument to the C mmap function is type off_t, not uintptr. On some 32-bit systems, off_t is larger than uintptr. Based on patch by Sören Tempel. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/445735
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. Based on patch by Sören Tempel. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/434755
2022-09-27runtime: synchronize empty struct field handlingmelonedo1-4/+10
In GCCGO and gollvm, the logic for allocating one byte for the last field is: 1. the last field has zero size 2. the struct itself does not have zero size 3. the last field is not blank this commit adds the last two conditions to runtime.structToFFI.

This ports https://go.dev/cl/421879 to libgo. This is a quick port to update gofrontend to work with the version of cgo in gc mainline. A more complete port will follow, changing the gc version of cmd/cgo to choose an approach based on feature testing the gccgo in use.

This fixes a build issue on musl libc where the same signal number is used for SIGIO and SIGPOLL. This causes a compilation error since the signal numbers must be unique for the signal table. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/400595
2022-04-18runtime: add special handling for signal 34A. Wilcox2-2/+5
The musl libc uses signal 34 internally for setgid (similar to how glibc uses signal 32 and signal 33). For this reason, special handling is needed for this signal in the runtime. The gc implementation already handles the signal accordingly. As such, this commit intends to simply copy the behavior of the Google Go implementation to libgo.

Revert CL 245098. It caused incorrect initialization ordering. Adjust the runtime package to work even with the CL reverted. Original description of CL 245098: This avoids requiring an init function to initialize the variable. This can only be done if x is a static initializer. The go1.15rc1 runtime package relies on this optimization. The package has a variable "var maxSearchAddr = maxOffAddr".
