From 9448b0513e2eec020fbca9c10412b83df5027a16 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Mon, 22 Jul 2013 11:22:36 -0400 Subject: refactor headers, especially alltypes.h, and improve C++ ABI compat 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 --- arch/microblaze/bits/alltypes.h.in | 22 +++++++ arch/microblaze/bits/alltypes.h.sh | 127 ------------------------------------- arch/microblaze/bits/stdint.h | 11 ++-- 3 files changed, 27 insertions(+), 133 deletions(-) create mode 100644 arch/microblaze/bits/alltypes.h.in delete mode 100755 arch/microblaze/bits/alltypes.h.sh (limited to 'arch/microblaze/bits') diff --git a/arch/microblaze/bits/alltypes.h.in b/arch/microblaze/bits/alltypes.h.in new file mode 100644 index 00000000..f0ab35fa --- /dev/null +++ b/arch/microblaze/bits/alltypes.h.in @@ -0,0 +1,22 @@ +#define _Addr int +#define _Int64 long long + +TYPEDEF __builtin_va_list va_list;
