Hi Christophe, could you please confirm you svn revision please?
I do have done bootstrap and regression on both x86 and aarch64 before
commit this patch. I had forgotten to "svn add" one header file, but add
it
later.
The failures started with r244673, and are still present with r244687.
When did you add the missing file?
It was r244674, https://gcc.gnu.org/ml/gcc-cvs/2017-01/msg00689.html, so
should have been included in your code. The faliure looks strange to me
then, I will svn up and re-start a fresh bootstrap on AArch64.
The file is present in my git clone.
I'm not bootstrapping on AArch64, I'm building a cross-compiler on x86_64,
but it shouldn't matter.
Hi Christophe,
Thanks, I reproduced this on cross linux environment, the reason is the
header file is not included because of the inhabit_libc guard, while the
unwinder header file should always be included.
I will committed the attached patch as obvious, once I finished a fresh
bootstrap, cross elf, cross linux.
Thanks.
