      refactor headers, especially alltypes.h, and improve C++ ABI compat · 9448b051
      Rich Felker 提交于
      the arch-specific bits/alltypes.h.sh has been replaced with a generic
      alltypes.h.in and minimal arch-specific bits/alltypes.h.in.
      
      this commit is intended to have no functional changes except:
      - exposing additional symbols that POSIX allows but does not require
      - changing the C++ name mangling for some types
      - fixing the signedness of blksize_t on powerpc (POSIX requires signed)
      - fixing the limit macros for sig_atomic_t on x86_64
      - making dev_t an unsigned type (ABI matching goal, and more logical)
      
      in addition, some types that were wrongly defined with long on 32-bit
      archs were changed to int, and vice versa; this change is
      non-functional except for the possibility of making pointer types
      mismatch, and only affects programs that were using them incorrectly,
      and only at build-time, not runtime.
      
      the following changes were made in the interest of moving
      non-arch-specific types out of the alltypes system and into the
      headers they're associated with, and also will tend to improve
      application compatibility:
      - netdb.h now includes netinet/in.h (for socklen_t and uint32_t)
      - netinet/in.h now includes sys/socket.h and inttypes.h
      - sys/resource.h now includes sys/time.h (for struct timeval)
      - sys/wait.h now includes signal.h (for siginfo_t)
      - langinfo.h now includes nl_types.h (for nl_item)
      
      for the types in stdint.h:
      - types which are of no interest to other headers were moved out of
        the alltypes system.
      - fast types for 8- and 64-bit are hard-coded (at least for now); only
        the 16- and 32-bit ones have reason to vary by arch.
      
      and the following types have been changed for C++ ABI purposes;
      - mbstate_t now has a struct tag, __mbstate_t
      - FILE's struct tag has been changed to _IO_FILE
      - DIR's struct tag has been changed to __dirstream
      - locale_t's struct tag has been changed to __locale_struct
      - pthread_t is defined as unsigned long in C++ mode only
      - fpos_t now has a struct tag, _G_fpos64_t
      - fsid_t's struct tag has been changed to __fsid_t
      - idtype_t has been made an enum type (also required by POSIX)
      - nl_catd has been changed from long to void *
      - siginfo_t's struct tag has been removed
      - sigset_t's has been given a struct tag, __sigset_t
      - stack_t has been given a struct tag, sigaltstack
      - suseconds_t has been changed to long on 32-bit archs
      - [u]intptr_t have been changed from long to int rank on 32-bit archs
      - dev_t has been made unsigned
      
      summary of tests that have been performed against these changes:
      - nsz's libc-test (diff -u before and after)
      - C++ ABI check symbol dump (diff -u before, after, glibc)
      - grepped for __NEED, made sure types needed are still in alltypes
      - built gcc 3.4.6

      default features: make musl usable without feature test macros · c1a9658b
      Rich Felker 提交于
      the old behavior of exposing nothing except plain ISO C can be
      obtained by defining __STRICT_ANSI__ or using a compiler option (such
      as -std=c99) that predefines it. the new default featureset is POSIX
      with XSI plus _BSD_SOURCE. any explicit feature test macros will
      inhibit the default.
      
      installation docs have also been updated to reflect this change.

      _GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCE · 3b94daba
      Rich Felker 提交于
      this is ugly and stupid, but now that the *64 symbol names exist, a
      lot of broken GNU software detects them in configure, then either
      breaks during build due to missing off64_t definition, or attempts to
      compile without function declarations/prototypes. "fixing" it here is
      easier than telling everyone to add yet another feature test macro to
      their builds.
