| ## We currently have a hack in Writer.cpp:fixSectionAlignments() to force |
| ## p_vaddr(PT_TLS)%p_align(PT_TLS)=0, to work around bugs in some dynamic loaders. |
| |
| ## p_vaddr rounded down to p_align has TP offset -0x7000. |
| ## The first address of PT_TLS (p_vaddr) has TP offset (p_vaddr%p_align - 0x7000). |
| ## Once we delete the hack, it is likely p_vaddr%p_align != 0. |
