Is it a bug in lld? Regards, Alexandre

...so. :)) It has a cdrecord-wodim-compatibility mode described in man 1 xorrecord. Formatting is done by: xorrecord -v dev=/dev/sr0 blank=format_overwrite The native command mode is more versatile but demands learning new names and new rules. See man 1 xorriso. xorriso -outdev /dev/sr0 -format as_needed The mode "as_needed" formats what can be formatted and is not formatted yet. It throws no error if the medium is not suitable for formatting. Have a nice day :) Thomas

On PowerPC we have a failing address sanitizer test when linking with LLD. The issue is that the symbol '__libc_stack_end' is resolved to an undefined weak symbol when linking with LLD but not when linking (with the exact same command/input) with other linkers. Tracing the symbol I see it is resolved to a definition in the dynamic linker as expected:

...these options are add-ons which you will not find in mkisofs. Vice versa, several mkisofs options are not supported by xorriso -as mkisofs. Most notably: -udf, -hfs. You may also use xorriso to put the ISO image onto optical media on GNU/Linux, FreeBSD, or Solaris: xorriso -as cdrecord -v blank=as_needed -eject output.iso (Documented in man xorrecord.) Send bug reports or enhancement wishes to me directly or to bug-xorriso at gnu.org Have a nice day :) Thomas
