Bug #: 52096
Summary: -dumpmachine does not respect -m32
Classification: Unclassified
Product: gcc
Version: 4.4.3
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: driver
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: matze@braunis.de
On a x86_64-linux-gnu machine calling
gcc -m32 -dumpmachine
gives
x86_64-linux-gnu
while I would have expected something like
i686-linux-gnu
Docu says "print the compilers target machine" in the presence of "-m32" I'm
not sure that the right answer would be. The most usefull answer for me would
be i686-linux-gnu, as I am using gcc -dumpmachine in my makefiles and users
passing in CFLAGS="-m32" break the build.

It should not be made multilib aware. If you want to make sure you are compiling for 32bit, then check the preprocessed predefines instead. ^ permalink raw reply [flat|nested] 3+ messages in thread
