new patch
Next try using symtab_real_symbol_p. Works better, but I now fail to
rename multiple uses of
static inline void
unread_char (int ch)
{
if (ch == '\n')
read_md_lineno--;
ungetc (ch, read_md_file);
}
from read-md.h during bootstrap (thus, with C++). symtab_real_symbol_p returns
false for
_ZL11unread_chari/2124 (unread_char) @0x7ffff5feb9c0
Type: function
Visibility:
next sharing asm name: 2108
previous sharing asm name: 2125
References: read_md_lineno/1445 (read)read_md_lineno/1445

Referring:
Function unread_char/2124 is inline copy in read_rtx_code/460
Clone of _ZL11unread_chari/428

Function flags: analyzed local finalized
Called by: _ZL17read_rtx_variadicP7rtx_def/462 (0.01 per call) (inlined)
Calls: ungetc/515 (0.01 per call)
but we still stream its IL (and thus I get section conflicts)?
We also have non-inlined copies:

Not sure how I can make a reproducer, the following works
static inline int foo (int i) { asm("#"); asm("#"); asm ("#"); asm
("#");asm("#"); asm("#"); asm ("#"); asm ("#");asm("#"); asm("#"); asm ("#");
asm ("#");asm("#"); asm("#"); asm ("#"); asm ("#");asm("#"); asm("#"); asm
("#"); asm ("#" : : "g" (&i)); asm("#"); asm("#"); asm ("#"); asm ("#");
return i/10; }
int __attribute__((flatten)) bar (int j)
{
return foo (j);
}
int main()
{
return foo (0) + bar (0) + foo (0);
}
