Bug ID: 16652
   Summary: ar manual suggests --plugin can come before the
operation code on the command line
   Product: binutils
   Version: 2.24
Status: NEW
  Severity: normal
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: jamborm at gcc dot gnu.org

The man page of ar suggests that --plugin parameter can come before
the operation code on the command line in the SYNOPSIS.  However, if
you try to put --plugin before an operation code, ar will fail
claiming that "no operation [was] specified."

[Bug gas/31903] New: Asan heap-buffer-overflow in test gas/elf/dwarf-5-irp.s in cross-assember to aarch64-elf

2024-06-17 Thread jamborm at gcc dot gnu.org

Bug ID: 31903
   Summary: Asan heap-buffer-overflow in test
gas/elf/dwarf-5-irp.s in cross-assember to aarch64-elf
   Product: binutils
   Version: unspecified
Status: NEW
  Severity: normal
  Priority: P2
 Component: gas
  Assignee: unassigned at sourceware dot org
  Reporter: jamborm at gcc dot gnu.org
  Target Milestone: ---

When configuring binutils revision c3d23f753da with:

  ../src/configure --prefix=/home/mjambor/binutils/inst --build=x86_64-linux
--disable-gdb --disable-gdbserver --disable-werror --enable-obsolete
--target=aarch64-elf CFLAGS="-g -O2 -fsanitize=address,undefined -Wno-error"
CXXLAGS="-g -O2 -fsanitize=address,undefined -Wno-error" LDFLAGS="-ldl"

silencing leak detection with:

  export  ASAN_OPTIONS=detect_leaks=0

buiding binutils and then, in the build gas subdirectory, running:

  make -k check RUNTESTFLAGS="elf.exp=dwarf-5-irp.s"

Results in FAIL of test "elf line."

In test log, there is an AddressSanitizer heap-buffer-overflow error:

Executing on host: sh -c {../as-new  --gdwarf-5  -o tmpdir/dwarf-5-irp.o
/home/mjambor/binutils/src/gas/testsuite/gas/elf/dwarf-5-irp.s 2>&1}  /dev/null

gas: extend \+ support to .rept

PR gas/31752

While not quite as macro-like as .irp / .irpc, this perhaps benefits from
supporting \+ even more than those: It allows, where desired, to get away
without maintaining an explicit count variable in source code.

Keep .rep (and custom per-arch uses of s_rept() / do_repeat()) behavior
unaltered.
