This patch fixes part of bug 26647 (-Werror=array-parameter error building with GCC 11 because of __sigsetjmp being declared using an array parameter in one header and a pointer parameter in another). The fix is to split the struct __jmp_buf_tag definition out to a separate bits/types/ header so it can be included in pthread.h, so that pthread.h can declare __sigsetjmp with the type contents visible, so can use an array (as in setjmp.h) rather than a pointer in the declaration. Note that several other build failures with GCC 11 remain. This does not fix the jmp_buf-related -Wstringop-overflow errors (also discussed in bug 26647), or -Warray-parameter errors for other functions (bug 26686), or -Warray-bounds errors (bug 26687). Tested, with older compilers, natively for x86_64 and with build-many-glibc.py for aarch64-linux-gnu. Tested with build-many-glibcs.py with GCC mainline for aarch64-linux-gnu that this gets past the -Warray-parameter issue for __sigsetjmp (with the next build failure being the other one discussed in bug 26647). |
