From: Weimin Pan Date: Sat, 26 Aug 2017 00:33:25 +0000 (-0500) Subject: Unbreak gdb build on 32-bit host with ADI support X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=654670a4f0928e3eddc6395d6804deb2e61a0614;p=binutils-gdb.git Unbreak gdb build on 32-bit host with ADI support The problem of failing to build with arm-linux-gnueabihf-g++-4.8 was that type CORE_ADDR is of "unsigned long" on a 64-bit machine so it's OK to use %lx but is of type "unsigned long long" on a 32 bit system. Fixed the problem in three places - (1) use a temp variable of type CORE_ADDR as argument 3 when calling target_auxv_search() then assign its value to "blksize" and "nbits" in 2 calls; (2) redo adi_normalize_address() using masks and xor operators to calculate normalized address; (3) call paddress() to print CORE_ADDR in either printf_filtered() or error(). Thank you, Pedro, for all your suggestions. gdb/ChangeLog: 2017-08-31 Weimin Pan * sparc64-tdep.c (adi_stat_t): Fix comment formatting. (adi_available): Use a temp variable of type CORE_ADDR as argument 3 when calling target_auxv_search. (adi_normalize_address): Use masks and xor operators to calculate normalized address.
