Bug ID: 115543
Summary: DWARF call_site_parameter entries are not generated
for stack-passed parameters
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: spevnev16 at gmail dot com
Target Milestone: ---
When compiling a C function with more than 6 parameters on x86_64, its
call_site contains only the first 6 parameters, while the others (which are
passed through stack rather than registers) only have formal_parameters in the
subprogram DIE.
I assume that the number 6 is related to the way parameters are passed on
x86_64 (i.e. only 6 are passed through registers) and thus this number may
differ based on the architecture.
version: 14.1.0
target: x86_64-linux-gnu
configured: /usr/src/gcc/configure --build=x86_64-linux-gnu --disable-multilib
--enable-languages=c,c++,fortran,go
compiled with: gcc -g3 -O1 -Wall -Wextra -pedantic main.c
