Re: [trans-mem,darwin] PR/52042 find tm_clone_table with PIE


Can I ask you to close this PR?
Indeed, my bugzilla account is a simple one and I cannot to change the bug status...

The problem in this PR is that with PIE, getsectdata does not return the
position of tm_clone_table after the relocation.
While _dyld_get_image_vmaddr_slide(0) is enough for PIE, this is not
enough for dylib.
I did not find an easy API function to get position of the
tm_clone_table for a shared library (dylib). So the only way I found is
to get the mach_header address of the current dylib (via
_dyld_get_image_header_containing_address), iterate over loaded binaries
to find the current shared library and use _dyld_get_image_vmaddr_slide
to find the position.
Any other proposal (my knowledge of darwin is really limited)?

Can someone do a bootstrap and test libitm on darwin (I have a limited
access to a darwin machine, at least libitm tests pass)? Thanks!

If tests passed, ok for 4.7?
