39ecc7a8c1 Use those functions in stack_walked.cpp test 2018-04-27 11:06:25 +02:00

f587eadbcc Add a tentative stack walker using eh_elfs
This is only a beginning: this does so far load the appropriate
eh_elf.so files and read a context. Unwinding is still absent.

be221f68d5 Check mtime to avoid recreating existing so 2018-04-26 19:15:37 +02:00
353a97c49d Refactor code generation: use shared/context_struct.h

implementation as well

771aec2621 Remove debug output 2018-04-25 17:49:02 +02:00
ff0f8c90df Allow unimplemented registers to appear in DWARF
The presence of such a register — eg. rcx, which is actually used in CFA
on a few lines of libgcc_s.so on my system — will yield an assert(0) in
the produced code, but will at least not fail to compile alltogether.
