Bug ID: 16288 Summary: Specifying an ISA in a .set directive causes a warning if "lower" than set from command-line Product: binutils Version: 2.25 (HEAD) Status: NEW Severity: normal Priority: P2 Component: gas Assignee: unassigned at sourceware dot org Reporter: hp at sourceware dot org Target: mips*-* Seen with recent master of binutils, for example 310bf259c3524c2954; from code-inspection likely to be present for 2.24 as well. The following construct is common with in-lined code (seen in alsa-lib and userspace-rcu), but gets a warning if the setting is "lower" than one specified on the command-line. For a mips-elf target and a file s.s, with the contents: .set push .set mips2 nop .set pop Observe: $ gas/as-new s.s $ gas/as-new -march=34kc s.s s.s: Assembler messages: s.s:2: Warning: the `dsp' extension requires MIPS32 revision 2 or greater s.s:2: Warning: the `mt' extension requires MIPS32 revision 2 or greater Note that the warning comes from the ".set mips2" directive, regardless of whether it's followed by code; the test-case can actually be reduced to that single line. The -march option comes from gcc when specifying the same option or from the configuration. The warning is bogus; the .set implementation seems to miss clearing command-line-specified ASEs when specifying an ISA. I believe that is how it's intuitively should work; this warning is a regression from, like, 8 months ago. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
