Bug #: 55515
Summary: PowerPC EABI: Create a predefined symbol for
-mdata=xxx
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rdiezmail-...@yahoo.de
I am investigating this issue:
http://sourceware.org/ml/newlib/2011/msg00295.html
If that link does not work, search the mailing list for "PowerPC EABI issues
with newlib".
During the investigation, I have missed a way to tell which -mdata=xxx option
is being used at the moment. That is, I need a predefined symbol like
_PPC_MSDATA=EABI, _PPC_MSDATA_EABI or similar. With such a symbol, it would be
easy to #error if the user has specified the wrong compiler flags.
Info about where to look in GCC's source code is here:
http://gcc.gnu.org/ml/gcc-help/2011-07/msg00079.html
If that link does not work, search the mailing list for "How to check at
compilation time whether -msdata is set to eabi for PowerPC embedded targets".
