The check is introduced by the following commit in v2.31. + +https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h= +67f846b59b32f3d704c601669409c2584383fea9 + +The here-doc usage in this script creates temporary file in /tmp. When we run in +an environment where /tmp has rarely been used, the newly created temporary file +may have a very low inode number. If the inode number was 6 which is the same as +/dev/null, the as would wrongly think the input file and the output file are the +same and report the following error. + +*** Compiler lacks asm-goto support.. Stop. + +One observed case happened in docker where the /tmp could be so rarely used that +very low number inode may be allocated and triggers the error. + +The fix below for the bug only exists on the master branch of binutils so far +and has not been released from upstream. As the convict is introduced since +v2.31, only v2.31 is affected. + +https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h= +2a50366ded329bfb39d387253450c9d5302c3503 + +When building linux-libc-headers we need to use "as" in binutils which does not +contain the fix for the moment. To work around the error, we create a fixed +temporary file to contain the program being tested. + +This patch also removes ">/dev/null 2>&1" so we will have more direct error +information in case something else wrong happened. + +Upstream-Status: Inappropriate [A work around for binutils v2.31] + +Signed-off-by: He Zhe <zhe.he@windriver.com> +--- + scripts/gcc-goto.sh | 5 ++++- + 1 file changed, 4 insertions(+), 1 deletion(-) + +diff --git a/scripts/gcc-goto.sh b/scripts/gcc-goto.sh +index 083c526..8dfac55 100755 +--- a/scripts/gcc-goto.sh ++++ b/scripts/gcc-goto.sh +@@ -3,7 +3,7 @@ + # Test for gcc 'asm goto' support + # Copyright (C) 2010, Jason Baron <jbaron@redhat.com> + +-cat << "END" | $@ -x c - -c -o /dev/null >/dev/null 2>&1 && echo "y" ++cat << "END" > ./input + int main(void) + { + #if defined(__arm__) || defined(__aarch64__) +@@ -20,3 +20,6 @@ entry: + return 0; + } + END ++ ++$@ -x c ./input -c -o ./output && echo "y" ++rm ./input ./output +-- +2.7.4 + |
