User-agent: mu4e 0.9.13; emacs 24.5.1 Hi,
Apologies for the bad posting style (I don't have the original email handy), but shouldn't _gnu_cmse_nonsecure_call be defined with the .global directive in the below hunk (to make it visible when linking)? diff --git a/libgcc/config/arm/cmse_nonsecure_call.S b/libgcc/config/arm/cm= se_nonsecure_call.S new file mode 100644 index 0000000000000000000000000000000000000000..bdc140f5bbe87c6599db225b1b9= b7bbc7d606710 --- /dev/null +++ b/libgcc/config/arm/cmse_nonsecure_call.S @@ -0,0 +1,87 @@ +.syntax unified +.thumb +__gnu_cmse_nonsecure_call: Right now, it ends up as a local symbol, and compiling and linking a program with cmse_nonsecure_call (say cmse-11.c), results in a linker error - the linker doesn't find the symbol even if it is present in libgcc.a. I found the problem that way - dumping symbols for my variant of libgcc.a and grepping showed the symbol to be available but local. Regards Senthil
