[PATCH v2] toolchain,glibc: Allow ARC big endian glibc builds

2019-11-05 Thread Vineet Gupta
Apparently big endian glibc builds just work, if we let the endian header allow that (which prev was #error). So this patch bumps glibc to version which fixes the header (this hopefully will become arc-2019.09-release) and then enables arceb in glibc toolchain builds Signed-off-by: Vineet Gupta

Currently for hard float we need to check for __ARC_FPU_SP__ || __ARC_FPU_DP__ and for soft float inverse of that. So define single convenience macros for either cases gcc/ -xx-xx Vineet Gupta * config/arc/arc-c.c (arc_cpu_cpp_builtins): Add __arc_hard_float__, __ARC_HAR

[PATCH 00/50] Add log level to show_stack()

2019-11-05 Thread Dmitry Safonov
Add log level argument to show_stack(). Done in three stages: 1. Introducing show_stack_loglvl() for every architecture 2. Migrating old users with an explicit log level 3. Renaming show_stack_loglvl() into show_stack() Justification: o It's a design mistake to move a business-logic decision int

[PATCH 03/50] arc: Add show_stack_loglvl()

2019-11-05 Thread Dmitry Safonov
Currently, the log-level of show_stack() depends on a platform realization. It creates situations where the headers are printed with lower log level or higher than the stacktrace (depending on a platform or user). Furthermore, it forces the logic decision from user to an architecture side. In resu
