From: Andrew Burgess Date: Tue, 6 Mar 2018 12:31:07 +0000 (+0000) Subject: gdb/riscv: Fixes to printf format strings X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cab5bb9d1f9fcf674d5b4c82aba7622597b1fd35;p=binutils-gdb.git gdb/riscv: Fixes to printf format strings Some of the format strings used in the new riscv target were incorrect, resulting in build failures on some hosts. This commit does the following: 1. Uses core_addr_to_string for formatting CORE_ADDR types. 2. Fixes legacy use of stderr for logging in one place that got missed, instead gdb_stdlog is used. 3. Re-indent a few printf related lines that were wrong. This should resolve some (but not all) of the build failures the new riscv target introduced. gdb/ChangeLog: * riscv-tdep.c (riscv_print_arg_location): Add header comment, change parameter type. Use GDB's print functions, and use core_addr_to_string where appropriate. (riscv_push_dummy_call): Use core_addr_to_string where appropriate, update call to riscv_print_arg_location, and reindent a few lines. (riscv_return_value): Update call to riscv_print_arg_location. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 793c99156b5..9567102043c 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,13 @@ +2018-03-06 Andrew Burgess + + * riscv-tdep.c (riscv_print_arg_location): Add header comment, + change parameter type.
