- Subject: [committed] Allocate subspace for tm data on 32-bit hppa-hpux
- Reply-to: John David Anglin <dave dot anglin at nrc-cnrc dot gc dot ca>
The attached patch fixes a slew testsuite of ICEs in default_no_named_section.
The patch creates a subspace/section for tm data. This resolves all the ICEs.
Tested on hppa2.0w=hp-hpux11.11 and hppa64-hp-hpux11.11. Committed to trunk.
