From 490f286d157dd83c0ef5721593e9d62e3cb05e83 Mon Sep 17 00:00:00 2001 From: Rui Ueyama Date: Mon, 27 Oct 2014 08:16:18 +0000 Subject: [PATCH] Re-commit r220667. C++ source given to check_cxx_source_compile should have define "main". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220669 91177308-0d34-0410-b5e6-96231b3b80d8 --- autoconf/configure.ac | 6 +- cmake/config-ix.cmake | 8 +- configure | 371 ++---------------------------------------- 3 files changed, 22 insertions(+), 363 deletions(-) diff --git a/autoconf/configure.ac b/autoconf/configure.ac index a198280f23d..618cf8b4db6 100644 --- a/autoconf/configure.ac +++ b/autoconf/configure.ac @@ -1592,8 +1592,12 @@ AC_HEADER_SYS_WAIT AC_HEADER_TIME AC_LANG_PUSH([C++]) -AC_CHECK_HEADERS([cxxabi.h]) +dnl size_t must be defined before including cxxabi.h on FreeBSD 10.0. +AC_CHECK_HEADERS([cxxabi.h], [], [], +[#include +]) AC_LANG_POP([C++]) + AC_CHECK_HEADERS([dlfcn.h execinfo.h fcntl.h inttypes.h link.h]) AC_CHECK_HEADERS([malloc.h setjmp.h signal.h stdint.h termios.h unistd.h]) AC_CHECK_HEADERS([utime.h]) diff --git a/cmake/config-ix.cmake b/cmake/config-ix.cmake index 8139d57ff83..5204f6c77ae 100755 --- a/cmake/config-ix.cmake +++ b/cmake/config-ix.cmake @@ -42,7 +42,6 @@ function(check_type_exists type files variable) endfunction() # include checks -check_include_file_cxx(cxxabi.h HAVE_CXXABI_H) check_include_file(dirent.h HAVE_DIRENT_H) check_include_file(dlfcn.h HAVE_DLFCN_H) check_include_file(errno.h HAVE_ERRNO_H) @@ -81,6 +80,13 @@ check_symbol_exists(FE_INEXACT "fenv.h" HAVE_DECL_FE_INEXACT) check_include_file(mach/mach.h HAVE_MACH_MACH_H) check_include_file(mach-o/dyld.h HAVE_MACH_O_DYLD_H) +# size_t must be defined before including cxxabi.h on FreeBSD 10.0. +check_cxx_source_compiles(" +#include +#include +int main() { return 0; } +" HAVE_CXXABI_H) + # library checks if( NOT PURE_WINDOWS ) check_library_exists(pthread pthread_create "" HAVE_LIBPTHREAD) diff --git a/configure b/configure index 17a81154aa8..c9373b55aea 100755 --- a/configure +++ b/configure @@ -773,7 +773,6 @@ USE_INTEL_JITEVENTS XML2CONFIG LIBXML2_LIBS LIBXML2_INC -CXXCPP HAVE_PTHREAD HAVE_LIBZ HUGE_VAL_SANITY @@ -807,8 +806,7 @@ CPPFLAGS CXX CXXFLAGS CCC -CPP -CXXCPP' +CPP' ac_subdirs_all='projects/test-suite projects/llvm-test projects/poolalloc @@ -1487,7 +1485,6 @@ Some influential environment variables: CXX C++ compiler command CXXFLAGS C++ compiler flags CPP C preprocessor - CXXCPP C++ preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations. @@ -10953,285 +10950,24 @@ ac_compile='$CXX -c $CXXFLAGS $CPPFLAGS conftest.$ac_ext >&5' ac_link='$CXX -o conftest$ac_exeext $CXXFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5' ac_compiler_gnu=$ac_cv_cxx_compiler_gnu -ac_ext=cpp -ac_cpp='$CXXCPP $CPPFLAGS' -ac_compile='$CXX -c $CXXFLAGS $CPPFLAGS conftest.$ac_ext >&5' -ac_link='$CXX -o conftest$ac_exeext $CXXFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5' -ac_compiler_gnu=$ac_cv_cxx_compiler_gnu -{ echo "$as_me:$LINENO: checking how to run the C++ preprocessor" >&5 -echo $ECHO_N "checking how to run the C++ preprocessor... $ECHO_C" >&6; } -if test -z "$CXXCPP"; then - if test "${ac_cv_prog_CXXCPP+set}" = set; then - echo $ECHO_N "(cached) $ECHO_C" >&6 -else - # Double quotes because CXXCPP needs to be expanded - for CXXCPP in "$CXX -E" "/lib/cpp" - do - ac_preproc_ok=false -for ac_cxx_preproc_warn_flag in '' yes -do - # Use a header file that comes with gcc, so configuring glibc - # with a fresh cross-compiler works. - # Prefer to if __STDC__ is defined, since - # exists even on freestanding compilers. - # On the NeXT, cc -E runs the code through the compiler's parser, - # not just through cpp. "Syntax error" is here to catch this case. - cat >conftest.$ac_ext <<_ACEOF -/* confdefs.h. */ -_ACEOF -cat confdefs.h >>conftest.$ac_ext -cat >>conftest.$ac_ext <<_ACEOF -/* end confdefs.h. */ -#ifdef __STDC__ -# include -#else -# include -#endif - Syntax error -_ACEOF -if { (ac_try="$ac_cpp conftest.$ac_ext" -case "(($ac_try" in - *\"* | *\`* | *\\*) ac_try_echo=\$ac_try;; - *) ac_try_echo=$ac_try;; -esac -eval "echo \"\$as_me:$LINENO: $ac_try_echo\"") >&5 - (eval "$ac_cpp conftest.$ac_ext") 2>conftest.er1 - ac_status=$? - grep -v '^ *+' conftest.er1 >conftest.err - rm -f conftest.er1 - cat conftest.err >&5 - echo "$as_me:$LINENO: \$? = $ac_status" >&5 - (exit $ac_status); } >/dev/null; then - if test -s conftest.err; then - ac_cpp_err=$ac_cxx_preproc_warn_flag - ac_cpp_err=$ac_cpp_err$ac_cxx_werror_flag - else - ac_cpp_err= - fi -else - ac_cpp_err=yes -fi -if test -z "$ac_cpp_err"; then - : -else - echo "$as_me: failed program was:" >&5 -sed 's/^/| /' conftest.$ac_ext >&5 - - # Broken: fails on valid input. -continue -fi - -rm -f conftest.err conftest.$ac_ext - - # OK, works on sane cases.
