1 ;; -ffunction-sections previously resulted in call relocations against the
2 ;; .text.foo section symbol instead of the actual function symbol.
3 ;; However, that results in a relocation against a symbol without the LSB set,
4 ;; so the linker thinks it is not linking against a Thumb symbol.
5 ;; Check that we use a relocation against the symbol for calls to functions
6 ;; marked as dso_local (foo$local)
7 ;; NB: Right now only R_ARM_PREL31 and R_ARM_ABS32 are converted to section
8 ;; plus offset, so this test can't use a call.
