Re: invalid expression as operand in aarch64 inline asm

-bits of ANCHOR0 we should be ensuring it is aligned to 8-bytes (or less than 256 - but we can't necessarily tell that at compile time). So I think your patch is correct - the symbol needs to be aligned to the size of the thing the symbol points to. Thanks, Matt -- Matthew Gretton-Dann Linaro

Re: compiler crash while building c++ libs

: 0 0 0 Yes this means you have no swap on your system. But you do have 1GB of memory of which about 575 MB is free, so I would still say the evidence is that this test case is using excessive amounts of memory and so raising a bug report would be useful. Thanks, Matt -- Matthew Gretton-Dann
