◆ ctf_preprocess()
|
static |
CTF preprocessing.
After the CTF types for the compilation unit have been generated fully, the
compiler writes out the asm for the CTF types.
CTF writeout in the compiler requires two passes over the CTF types. In the
first pass, the CTF preprocess pass:
1. CTF types are sorted in the order of their type IDs.
2. The variable number of bytes after each CTF type record are calculated.
This is used to calculate the offsets in the ctf_header_t.
3. If the CTF type is of CTF_K_FUNCTION, the number of bytes in the
funcinfo sub-section are calculated. This is used to calculate the
offsets in the ctf_header_t.
4. Keep the list of CTF variables in ASCIIbetical order of their names.
In the second pass, the CTF writeout pass, asm tags are written out using
the compiler's afore-generated internal pre-processed CTF types.
