While gcc compilation on sparc is rare I'm not sure that simply deleting the sparc-only option unconditionally is the right thing to do.
I thought about that too. But I was unable to find info on OpenJDK + SPARC + Linux. Is that combination even supported? The README doesn't list it: http://hg.openjdk.java.net/jdk6/jdk6/raw-file/tip/README-builds.html#MBE Linux-sparc is not one of Oracle's supported OpenJDK platforms. However AFAIK there are people in the community building OpenJDK on Linux-sparc using the Zero interpreter. I don't know if this would affect them but it still seems to me that we should be careful not to break other people's builds. With FOSDEM and subsequent security errata, this got pushed to side. Sorry for the delay. I've created a new webrev which contains a special case for the Sparc family (on Linux): http://cr.openjdk.java.net/~dbhole/GCC-4.7-JDK8.01/
Where is ARCH_FAMILY being set?

If it is okay for push, please go ahead and push it (I don't have commit access). I will then propose it for 7u.
Thanks, Deepak

The option seemed more like a relic from Solaris + SPARC config rather than a requirement for Linux + SPARC.

JDK builds currently fail with GCC 4.7 due to its stricter option checking. GCC 4.6 and prior ignored invalid options -- GCC 4.7 does not. Certain files in JDK supply the -mimpure-text option to GCC. This option is only valid on SPARC[1,2]. As a result, GCC 4.7 throws an error during build on Linux (I suppose . This patch removes the option: http://cr.openjdk.java.net/~dbhole/GCC-4.7-JDK8.00 1: http://gcc.gnu.org/onlinedocs/gcc-3.3.6/gcc/SPARC-Options.html 2: http://gcc.gnu.org/onlinedocs/gcc-3.3.6/gcc/i386-and-x86002d64-Options.html If OK for push, please feel free to do so (I don't have commit access).
