Subject: [PATCH 18/18] Temporary workaround for ppc on ppc
|
|
|
4e10e2c |
|
|
|
4e10e2c |
target-ppc/translate.c puts values of type opcode_t into .opcodes
|
|
|
4e10e2c |
section, using GCC extension to do so, and hoping that this will make
|
|
|
4e10e2c |
them appear contiguously and in the source order in the resulting
|
|
|
4e10e2c |
executable. This assumption is not safe and is known to be violated
|
|
|
4e10e2c |
with certain versions of GCC, certain flags passed to it and on
|
|
|
4e10e2c |
certain platforms (gcc 4.3.0, -O and PPC/PPC64 for instance)
|
|
|
4e10e2c |
|
|
|
4e10e2c |
The workaround consists of adding -fno-unit-at-a-time to the list of
|
|
|
4e10e2c |
GCC command line options while building PPC translate.o on a PPC.
