[Lldb-commits] [PATCH] D65282: ObjectFileELF: permit thread-local sections with overlapping file addresses

[Fangrui Song via Phabricator via lldb-commits]

MaskRay added inline comments.


================
Comment at: lit/Modules/ELF/PT_LOAD-overlap-PT_TLS.yaml:62
+    Flags:           [ SHF_ALLOC, SHF_WRITE ]
+    Address:         0x1000
+    AddressAlign:    0x4
----------------
`.data = .tbss = 0x1010` is a more realistic scenario.

Normally, a SHT_PROGBITS section may overlap with a SHT_NOBITS section, but two SHT_PROGBITS sections do not overlap (ld has an on-by-default check `ld --check-sections`). Linkers allocate file bytes for SHT_PROGBITS sections so their occupied bytes cannot be reused by other sections (without fixing addresses with a linker script).
