Date: Wed, 26 Jun 2019 13:50:29 -0400 Message-Id: <20190626175029.4699-16-zackw@panix.com> In-Reply-To: <20190626175029.4699-1-zackw@panix.com> References: <20190626175029.4699-1-zackw@panix.com> MIME-Version: 1.0 sys/ucontext.h is effectively a bits header. Its contents are extremely system-specific, and it’s strongly associated with a specific public header (ucontext.h) that provides a superset of its definitions, but there are other public headers that also require some of its definitions. This patch therefore moves it into the bits/ namespace and adjusts all the headers that refer to it. In case there are external users, a stub is added that includes ucontext.h. Most of the fallout changes are trivial, but aarch64, ia64 and riscv need a little more work. aarch64 sys/ucontext.h (now bits/ucontext.h) was including sys/procfs.h for the definition of elf_greg_t etc; the simplest fix is to have it include bits/procfs.h instead (and then that needs to include sys/user.h for user_regs_struct). This is not ideal but fixing it properly would require disentangling all of the debugger interface headers which is more than I’m up for at the moment. ia64 bits/ptrace.h and bits/procfs.h were both including bits/sigcontext.h, which is only licensed to be included from signal.h. (I’m not sure how this ever worked, or why it broke with this patch and not some previous one.) This is fixed by creating another single-type header, bits/types/__ia64_fpreg.h, which provides the only thing they need from bits/sigcontext.h. s/u/s/l/riscv/makecontext.c was defining makecontext with a function head that didn’t agree with its official prototype (in ucontext.h); formerly that file did not include ucontext.h, only sys/ucontext.h, so we were getting away with it, but it’s still wrong. Making the function head match the prototype actually simplifies the code. * sysdeps/generic/sys/ucontext.h: Move to top level bits/ucontext.h.
