ldso/mips: Enable bootstrap relocations
_dl_reltypes_tab[] is an array of pointers to constant strings:
Contents of section .data:
20000 01000000 02000000 00000000 00000000 ................
20010 70e50000 7ce50000 88e50000 94e50000 p...|...........
^^^^^^^^ ^^^^^^^^ ^^^^^^^^ ^^^^^^^^
(pointers are LE)
Contents of section .rodata:
e570 525f4d49 50535f4e 4f4e4500 525f4d49 R_MIPS_NONE.R_MI
e580 50535f31 36000000 525f4d49 50535f33 PS_16...R_MIPS_3
e590 32000000 525f4d49 50535f52 454c3332 2...R_MIPS_REL32
These pointers require relocation:
DYNAMIC RELOCATION RECORDS
OFFSET TYPE VALUE
00000000 R_MIPS_NONE *ABS*
0001fffc R_MIPS_REL32 *ABS*
00020010 R_MIPS_REL32 *ABS*
00020014 R_MIPS_REL32 *ABS*
00020018 R_MIPS_REL32 *ABS*
On MIPS, only GOT relocations are currently handled by ldso during
startup. The net effect is that when running with "LD_DEBUG=reloc",
ldso itself crashes before the program even starts. This is caused
by _dl_dprintf() dereferencing an unadjusted string pointer such as
0xe570.
This patch enables the missing relocations and allows LD_DEBUG to work
as designed.
