[Bug target/18615] New: biarch bootstrap fails on sparc-linux (CVS 20041121)

[debian-gcc at lists dot debian dot org]

this is not a standard setup, Eric Botcazou suggested to bring up the issue
here. For 3.3.x, 3.4.x and some versions before, Debian uses a biarch setup,
defaulting the compiler to 32bit, and having additional support for 64bit. With
current mainline this setup currently bootstraps, but fails to build the 64bit
libstdc++. A similiar failure in libstdc++ is seen, when configuring a biarch
compiler for ix86/x86_64, defaulting to ix86 (will open a separate report).

No, bootstrap on sparc64-linux fails earlier in stage2, submitted as PR18622.

simplify_gen_subreg was seriously shaken recently.  Would you mind updating and
trying again?

Great!  The number of Ada failures is unexpected though, maybe related to the
change of calling conventions for complex types.

Btw, if the machine is available for some more hours, it would also be nice to
test both architectures in a row, with

  make -k check RUNTESTFLAGS="--target_board=unix{,-m64}"

('\' might be required before the '{' and '}', depending on the shell)
