Check that .byte directives do not generate a bogus overflow message. * gas/sh/too_large.s: New test control file. --- gas/ChangeLog | 6 ++++++ gas/config/tc-sh.c | 5 +++++ gas/testsuite/ChangeLog | 7 +++++++ gas/testsuite/gas/sh/basic.exp | 2 ++ gas/testsuite/gas/sh/too_large.d | 9 +++++++++ gas/testsuite/gas/sh/too_large.s | 39 +++++++++++++++++++++++++++++++++++++++ 6 files changed, 68 insertions(+) create mode 100644 gas/testsuite/gas/sh/too_large.d create mode 100644 gas/testsuite/gas/sh/too_large.s diff --git a/gas/ChangeLog b/gas/ChangeLog index e3c02c8..0b72f17 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,9 @@ +2006-07-12 Nick Clifton + + * config/tc-sh.c (md_apply_fix): Do not allow the generic code in + fixup_segment() to repeat a range check on a value that have + already been checked here. + 2006-07-07 James E Wilson * config/tc-mips.c (mips_cpu_info_table): Add sb1a. diff --git a/gas/config/tc-sh.c b/gas/config/tc-sh.c index 0abbe92..9d651de 100644 --- a/gas/config/tc-sh.c +++ b/gas/config/tc-sh.c @@ -4080,6 +4080,11 @@ md_apply_fix (fixS *fixP, valueT *valP, segT seg ATTRIBUTE_UNUSED) } if (max != 0 && (val < min || val > max)) as_bad_where (fixP->fx_file, fixP->fx_line, _("offset out of range")); + else if (max != 0) + /* Stop the generic code from trying to overlow check the value as well. + It may not have the correct value anyway, as we do not store val back + into *valP. */ + fixP->fx_no_overflow = 1; if (fixP->fx_addsy == NULL && fixP->fx_pcrel == 0) fixP->fx_done = 1; diff --git a/gas/testsuite/ChangeLog b/gas/testsuite/ChangeLog index a4cd0e9..fcec568 100644 --- a/gas/testsuite/ChangeLog +++ b/gas/testsuite/ChangeLog @@ -1,3 +1,10 @@ +2006-07-12 Nick Clifton + + * gas/sh/basic.exp: Run "too_large" dump test. + * gas/sh/too_large.s: New test file.
