OBJDUMP 2.19.1 (arm-linux-xxx-) : disassemble only first ARM instruction in .text

[PhW]

Hi!

Not found this bug in bugzilla database.

My guess : bad handling of the $a, $t, $d  symbols

Here is a trace on Debian testing (crosschain packages from emdebian.org)

[Bug gold/10133] no string merge in .shstrtab?

[ian at airs dot com]

--- Additional Comments From ian at airs dot com  2009-05-08 05:26 ---
gold currently only merges strings in string sections if you use -O2.  See the
comment around line 393 of stringpool.cc.  Does that make sense to you?  Perhaps
we should do the optimization if the string section size is small?
