- Subject: gcc-7: doesn't look for "as" in dir specified by -B
- From: Jakub Wilk <jwilk@jwilk.net>
- Date: Thu, 19 Apr 2018 00:31:03 +0200

Package: gcc-7
Version: 7.3.0-16
Control: block 895618 with -1
GCC no longer looks for "as" in the directory specified by the -B
option:
$ gcc --version | head -n1
gcc (Debian 7.3.0-16) 7.3.0
$ strace -f -o '| grep -w as' gcc -B/foo/bar/ -c -x c /dev/null
3641 access("/usr/bin/x86_64-linux-gnu-as", X_OK) = 0
3644 execve("/usr/bin/x86_64-linux-gnu-as", ["/usr/bin/x86_64-linux-gnu-as", "--64", "-o", "null.o", "/tmp/cc40S4xu.s"], 0x1ca26d0 /* 24 vars */ <unfinished ...>
This breaks afl-gcc (part of the afl package), which uses the -B option
to talk GCC into using a hacked version of the assembler.
I guess this is fallout from fixing #895251.
Previously it worked like this:
$ gcc --version | head -n1
gcc (Debian 7.3.0-15) 7.3.0
$ strace -f -o '| grep -w as' gcc -B/foo/bar/ -c -x c /dev/null

3770 stat("/usr/lib/gcc/x86_64-linux-gnu/7/../../../../x86_64-linux-gnu/bin/as", 0x7ffd82351450) = -1 ENOENT (No such file or directory)

3773 execve("/usr/bin/as", ["as", "--64", "-o", "null.o", "/tmp/ccFhN057.s"], 0xbe46d0 /* 24 vars */ <unfinished ...>
As you can see, GCC was already looking for "as" in a triplet-specific
directory. So perhaphs gcc-7 should ship an appropriate symlink in
/usr/lib/gcc/<triplet>/7/, instead of hardcoding path to "as" at
configure time?
