This patch to the Go frontend finalizes methods for type aliases of
struct types. Previously we would finalize the methods of the alias
type itself, but since its a type alias we really need to finalize the
methods of the aliased type.
This patch also handles method expressions of unnamed struct
This patch by Clément Chigot changes the Go frontend to call
runtime.eqtype for non-interface type switches on AIX. All type
switch clauses must call runtime.eqtype if the linker isn't able to
merge type descriptors pointers. Previously, only interface-type
clauses were doing it. This is for http

This libgo patch by Clément Chigot removes __go_ptrace on AIX. AIX
ptrace syscalls doesn't have the same semantic than the glibc one.
The syscall package is already handling it correctly so disable the
new __go_ptrace C function for AIX. Bootstrapped and ran Go testsuite
on x86_64-pc-linux-gnu.
This patch changes the libbacktrace tests to only run dsymutil when
building for Mach-O. This should fix GCC PR 97227. Bootstrapped and

This libbacktrace patch creates mtest.dsym when using dsymutil. This

I don't understand why this code uses symtab_indices_shndx at all.
There should only be one SHT_SYMTAB_SHNDX section. There shouldn't be
any need for the symtab_in
