Hi Pierre,
Only just saw your email turn up on the list!
This is bug 7150392 and was fixed about 6 weeks ago.
From the eval:
This option is causing some confusion as it was listed as a GCC sparc
option and so we had concerns about its need on linux-sparc, but then it
was changed to a Solaris2 option in 2010:
http://gcc.gnu.org/onlinedocs/gcc/Solaris-2-Options.html#index-mimpure_002dtext-2103
http://old.nabble.com/Correctly-document-Solaris-2-options-td29851048.html
So it's applicability to linux-sparc is unclear. As we only used this
option for linux builds and not Solaris builds I find this even more
confusing!

Hi OpenJDK people !
I tried to build the latest version of OpenJDK on my machine, but ran
into a problem during the compilation.
The error I got was "gcc: error: unrecognized command line option
'-mimpure-text'".
I am not a C/C++ programmer but I found out that this option is for
Solaris only. It is used at line 70 in the
file ./jdk/make/common/shared/Compiler-gcc.gmk
It seems that the problem is related to gcc v4.7, which is the version I
used. I found a JIRA on JRuby where a user had the same problem (see
"References" below).
I removed that option form the file Compiler-gcc.gmk and the build
was successful. Was that the right thing to do or should I expect JVM
crashes ?
I did not try to build the package using older versions of gcc, so I
suppose that previous versions did tolerate the presence of this flag
even if it is useful only on Solaris. Can someone confirm this ?
