The patch is a bit rough perhaps. What it does is this:

If the section isn't one of the default ones I use the specified name for the section, and defaults it to the TEXT segment, the S_ATTR_SOME_INSTRUCTIONS flag, and byte alignment. The segment can be overridden by a "segname " parameter to the section directive. (I wanted segname= to make it similar to the "CLASS" parameter in NASM/OMF, but I couldn't figure out how to convert parameter to a string.)

  • status changed from new to closed
  • resolution set to fixed

(In [1852]) Fix #102: Permit non-standard macho section names.

Two forms are legal ({} are replaceables): SECTION {segname} {sectname} SECTION {sectname} segname={segname} Also, SECTION {sectname} where sectname is unrecognized is also legal, defaults segname to TEXT, and generates a warning.
