gas/arm: Force output of a data mapping symbol for literal pools
If there is a a trailing align statement in a code section we may
output data padding with a data mapping followed by a code alignment
with a code mapping. The literal pool may then be output with a code
mapping symbol which will cause it to be endian swapped in a big-endian
configuration. When outputting a literal pool make sure that a data
mapping symbol is output in all cases.
gas/ChangeLog:
2014-04-23 Will Newton <will.newton@linaro.org>
* config/tc-arm.c (s_ltorg): Call make_mapping_symbol
directly instead of mapping_state.
gas/testsuite/ChangeLog:
2014-04-23 Will Newton <will.newton@linaro.org>
* gas/arm/mapmisc.d: Check literal pool mapping with
a trailing .align statement.
* gas/arm/mapmisc.s: Likewise.
