Subject: [RFC2 PATCH 00/23] ARM64: support ILP32
This series enables aarch64 port with ilp32 mode.
ABI details:
- types are taken from AARCH32, next types turned to 64-bit,
as modern requirement for new APIs tells:
ino_t is u64 type
off_t is s64 type
blkcnt_t is s64 type
fsblkcnt_t is u64 type
fsfilcnt_t is u64 type
- 64-bit arguments are passed in syscall as register pair,
as kernel internally clears top halves for all input regs;
- standard syscall table is used;
- 32-bit time_t is used. AARCH64/ILP32 is waiting for general
fix of Y2038 problem just like other 32-bit arches;
- stat{64}, statfs{64} structures are of the identical layout
with LP64. Corresponding syscalls are taken from 64-bit code
- struct utmp, utmpx layouts are the same.
v1: https://sourceware.org/ml/libc-alpha/2016-06/msg00730.html
v2:
- rebased on master;
- dropped unneeded/unrelated patches;
- pread family platform implementation removed;
- addressed v1 comments (I'm really sorry if I missed something,
there are a lot of them, and I am really thankfull for detailed review);
Tested with LTP. Regressions are like this:
abort01 FAIL 2
kill11 FAIL 2
mmap16 FAIL 6
open12 FAIL 2
rename11 FAIL 2
rmdir02 FAIL 2
umount2_01 FAIL 2
umount2_02 FAIL 2
umount2_03 FAIL 2
utime06 FAIL 2
It's better than v1, and there are ~5 additional regressions comparing to
aarch64, all are related to filesystem.
Andrew Pinski (17):
[AARCH64] define word size for lp64 and ilp32
[AARCH64] Add header guards to sysdep.h headers.
Add dynamic ILP32 AARCH64 relocations to elf.h
[AARCH64] Add PTR_REG, PTR_LOG_SIZE, and PTR_SIZE. Use it in
LDST_PCREL and LDST_GLOBAL.
[AARCH64] Use PTR_REG in crti.S.
[AARCH64] Use PTR_REG/PTR_SIZE/PTR_SIZE_LOG in dl-tlsesc.S
[AARCH64] Use PTR_* macros in dl-trampoline.S
[AARCH64] Use PTR_* in start.S
[AARCH64] Use PTR_REG in getcontext.S.
[AARCH64] Detect ILP32 in configure scripts.
[AARCH64] Add ILP32 support to elf_machine_load_address.
[AARCH64] Add ILP32 to makefiles
[AARCH64] Add support to ldconfig for ILP32 and libilp32
[AARCH64] Add ILP32 ld.so to the known interpreter names.
[AARCH64] Add ldd-rewrite.sed so that ilp32 ld.so can be found
[AARCH64] Make lp64 and ilp32 directories.
[AARCH64] Fix ILP32 warning
Yury Norov (6):
[AARCH64] ILP32: introduce syscalls that pass off_t
[AARCH64] ILP32: support stat syscall family
[AARCH64] delouse input arguments in system functions
[AARCH64] Make __SIZEOF_SEM_T 16 for ILP32
off_t: fix register pair calculation for 64-bit case
[AARCH64] Take utmp{,x}.h from s390 port
