1 /* This file tests that we can successfully call each compiler-rt function. It is 2 designed to check that the runtime libraries are available for linking and 3 that they contain the expected contents. It is not designed to test the 4 correctness of the individual functions in compiler-rt. 5 6 This test is assumed to be run on a 10.6 machine. The two environment 7 variables below should be set to 10.4 and 10.5 machines which can be directly 8 ssh/rsync'd to in order to actually test the executables can run on the 9 desired targets. 10 */ 11 12 // RUN: export TENFOUR_X86_MACHINE=localhost 13 // RUN: export TENFIVE_X86_MACHINE=localhost 14 // RUN: export ARM_MACHINE=localhost 15 // RUN: export ARM_SYSROOT=$(xcodebuild -sdk iphoneos -version Path) 16 17 // RUN: echo iPhoneOS, ARM, v6, thumb 18 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv6 -mthumb -c %s -o %t.o 19 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv6 -mthumb -v -Wl,-t,-v -o %t %t.o 1>&2 20 // RUN: rsync -arv %t $ARM_MACHINE:/tmp/a.out 21 // RUN: ssh $ARM_MACHINE /tmp/a.out 22 // RUN: echo 23 24 // RUN: echo iPhoneOS, ARM, v6, no-thumb 25 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv6 -mno-thumb -c %s -o %t.o 26 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv6 -mno-thumb -v -Wl,-t,-v -o %t %t.o 1>&2 27 // RUN: rsync -arv %t $ARM_MACHINE:/tmp/a.out 28 // RUN: ssh $ARM_MACHINE /tmp/a.out 29 // RUN: echo 30 31 // RUN: echo iPhoneOS, ARM, v7, thumb 32 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv7 -mthumb -c %s -o %t.o 33 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv7 -mthumb -v -Wl,-t,-v -o %t %t.o 1>&2 34 // RUN: rsync -arv %t $ARM_MACHINE:/tmp/a.out 35 // RUN: ssh $ARM_MACHINE /tmp/a.out 36 // RUN: echo 37 38 // RUN: echo iPhoneOS, ARM, v7, no-thumb 39 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv7 -mno-thumb -c %s -o %t.o 40 // RUN: %clang -isysroot $ARM_SYSROOT -arch armv7 -mno-thumb -v -Wl,-t,-v -o %t %t.o 1>&2 41 // RUN: rsync -arv %t $ARM_MACHINE:/tmp/a.out 42 // RUN: ssh $ARM_MACHINE /tmp/a.out 43 // RUN: echo 44 45 // RUN: echo 10.4, i386 46 // RUN: %clang -arch i386 -mmacosx-version-min=10.4 -c %s -o %t.o 47 // RUN: %clang -arch i386 -mmacosx-version-min=10.4 -v -Wl,-t,-v -o %t %t.o 1>&2 48 // RUN: %t 49 // RUN: echo 50 51 // RUN: rsync -arv %t $TENFOUR_X86_MACHINE:/tmp/a.out 52 // RUN: ssh $TENFOUR_X86_MACHINE /tmp/a.out 53 // RUN: echo 54 55 // RUX: rsync -arv %t $TENFIVE_X86_MACHINE:/tmp/a.out 56 // RUX: ssh $TENFIVE_X86_MACHINE /tmp/a.out 57 // RUN: echo 58 59 // RUN: echo 10.5, i386 60 // RUN: %clang -arch i386 -mmacosx-version-min=10.5 -c %s -o %t.o 61 // RUN: %clang -arch i386 -mmacosx-version-min=10.5 -v -Wl,-t,-v -o %t %t.o 1>&2 62 // RUN: %t 63 // RUN: echo 64 65 // RUN: rsync -arv %t $TENFIVE_X86_MACHINE:/tmp/a.out 66 // RUN: ssh $TENFIVE_X86_MACHINE /tmp/a.out 67 // RUN: echo 68 69 // RUN: echo 10.6, i386 70 // RUN: %clang -arch i386 -mmacosx-version-min=10.6 -c %s -o %t.o 71 // RUN: %clang -arch i386 -mmacosx-version-min=10.6 -v -Wl,-t,-v -o %t %t.o 1>&2 72 // RUN: %t 73 // RUN: echo 74 75 // RUN: echo 10.4, x86_64 76 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.4 -c %s -o %t.o 77 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.4 -v -Wl,-t,-v -o %t %t.o 1>&2 78 // RUN: %t 79 // RUN: echo 80 81 // RUN: rsync -arv %t $TENFOUR_X86_MACHINE:/tmp/a.out 82 // RUN: ssh $TENFOUR_X86_MACHINE /tmp/a.out 83 // RUN: echo 84 85 // RUN: rsync -arv %t $TENFIVE_X86_MACHINE:/tmp/a.out 86 // RUN: ssh $TENFIVE_X86_MACHINE /tmp/a.out 87 // RUN: echo 88 89 // RUN: echo 10.5, x86_64 90 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.5 -c %s -o %t.o 91 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.5 -v -Wl,-t,-v -o %t %t.o 1>&2 92 // RUN: %t 93 // RUN: echo 94 95 // RUN: rsync -arv %t $TENFIVE_X86_MACHINE:/tmp/a.out 96 // RUN: ssh $TENFIVE_X86_MACHINE /tmp/a.out 97 // RUN: echo 98 99 // RUN: echo 10.6, x86_64 100 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.6 -c %s -o %t.o 101 // RUN: %clang -arch x86_64 -mmacosx-version-min=10.6 -v -Wl,-t,-v -o %t %t.o 1>&2 102 // RUN: %t 103 // RUN: echo 104 105 #include <assert.h> 106 #include <stdio.h> 107 #include <sys/utsname.h> 108 109 typedef int si_int;
