--- Comment #5 from Khalil <kammce at google dot com> ---
Having similiar issues with ARM Embedded and Linux GCC.
Having trouble finding a work around for this.
Here is an example code that demonstrates the issue in our particular use case:
===============================================================
// g++ -std=c++17 static.cpp -o static.exe
//
// objdump -t static.exe | grep thing
// 0000000000000740 u O .rodata 0000000000000064
_ZZ5test0ILi5EEvvE5thing
//
// clang -std=c++14 static.cpp -o static.exe
// objdump -t static.exe | grep thing
// 00000000004005d3 w O .log_entry 0000000000000064

#include <cstdio>
#if __APPLE__
#define PUT_IN_SECTION(name) __attribute__((section("__text," name), used))
#else
#define PUT_IN_SECTION(name) __attribute__((section(name), used))
#endif
struct ThingType
{
constexpr ThingType(const char * str): data{}
{
for(int i = 0; str[i] != '\0' && i < sizeof(data); i++)
{
data[i] = str[i];
}
}
char data[100];
};
template <int dummy_template_parameter = 5>
void test0()
{
PUT_IN_SECTION(".log_entry")
static const ThingType thing("Goodbye!");
printf("Hello, World!\n");
}
int main()
{
test0();
return 0;
}
===============================================================
Comment the test0 template line out, and the entry will appear in the
appropriate section.
