+
+PR55681 observes that currently only one qualifier is allowed for
+inline asm, so that e.g. "volatile asm" is allowed, "const asm" is also
+okay (with a warning), but "const volatile asm" gives an error. Also
+"goto" has to be last.
+
+This patch changes things so that only "asm-qualifiers" are allowed,
+that is "volatile" and "goto", in any combination, in any order, but
+without repetitions.

+
+The Linux kernel people want a feature that makes GCC pretend some
+inline assembler code is tiny (while it would think it is huge), so
+that such code will be inlined essentially always instead of
+essentially never.
+
+This patch lets you say "asm inline" instead of just "asm", with the
+result that that inline assembler is always counted as minimum cost
+for inlining. It implements this for C and C++, making "inline"
+another asm-qualifier (supplementing "volatile" and "goto").
