2012-12-08HACKING: List areas where we may rely on impdef C behaviourPeter Maydell1-0/+20
Add a section to HACKING saying which version of the C spec we use and describing the bits of implementation defined C compiler behaviour which C code in QEMU is allowed to rely on. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-1/+1
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-10-05doc: update HACKING wrt strncpy/pstrcpyJim Meyering1-4/+5
Reword the section on strncpy: its NUL-filling is important in some cases. Mention that pstrcpy's signature is different. Signed-off-by: Jim Meyering <meyering@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15HACKING: clarify allocation/free recommendationsPeter Maydell1-4/+6
Clarify the allocation/free recommendations; this is mostly just tidying up following the global-search-and-replace done with the conversion to the GLib g_malloc and friends.

2011-02-25HACKING: Update status of format checkingStefan Weil1-3/+0
Hopefully all functions with printf like arguments now use format checking. This was tested with default build configuration on linux and windows hosts (including some cross compilations), so chances are good that there remain few (if any) functions without format checking. Therefore the last comment in HACKING is no longer valid but misleading.

2010-09-10HACKING: add C type rulesBlue Swirl1-0/+68
Add C type rules, adapted from libvirt HACKING. Also include a description of special QEMU scalar types. Move typedef rule from CODING_STYLE rule 3 to HACKING rule 6 where it belongs. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-09-10HACKING: add preprocessor rulesBlue Swirl1-0/+6
