AArch32: No more issues in libstdc++ as well (same as reasons as AArch64), and only 3 failures in the testsuite: - The first one is invalid as the test sans the assembler for "ldaex\tr\[0-9\]+..." and it fails because with LRA the chosen register is r12 and thus the instruction is "ldaex ip,..."
Fair enough - we should just fix the test and move on.
- The two others are the same bug where LRA keeps some REG_NOTES (DEAD and UNUSED) on a comparison pattern where reload removes then, and the results is that the comparison is removed. I'm currently working on this issue.
- Thumb still doesn't bootstrap.
I would suggest in addition a transitional command-line option to switch between LRA and reload as a temporary measure so that folks can do some more experimenting for AArch32.
I don't see why such a command-line option is wrong for A64 in principle but that's something for Marcus / Richard to comment.
