because:
- Constructing fp numbers isn't quite trivial
- 3 additional calls to strchr per number is noticeable slow
Also: exclude abitest.c:ret_longdouble_test2 on _WIN32
for mixed gcc/tcc scenario
test case:
- make -k test (on win32):
-2.120000 0.500000 23000000000.000000
+2.120000 0.500000 22999999999.999996
...
ret_longdouble_test2... failure
This reverts 857f7dbfa6
and deaee6c249
1: The new patch for the other machines still have the problem.
2: libcrt Rename (what if gcc had libcrt as well)
3: parse_number exact problem
4: VT_VLS is to allow tcc
Compile the following
int b = 9;
struct st {
int a;
int b [b]
};
struct st st1;
st1.b [8] = 9;
printf ("% d \ n", st1.b [8]);
tcc a problem. Due to problems in front, and now can not be improved
5: they commit much, bug difficult to lock, you can not let other people help develop.
6: ('\ t') too
Thanks to Michael and Ray
Their criticism I have benefited!
For example, it should look like this
High stack
-------------
----- Func_ret_sub
------------
---- Vla stack
-------------
---- Known loc
--------------
Low
Increased loc_stack () function is used for temporary stack management, call save_reg (), released by load ()
Like this
Before use
High
----- Known loc
----
---
----
---- Pop_stack
Low
loc_stack (size, 1)
After use
High
----- Known loc
---- Pop_stack
---
----
----
Low
The attached fix (libcrt.c) is just one example. There seem
many more such introduced from latest commits that look badly
formatted in anyone else's editors and should be fixed.
General recommended policy:
- if possible, do not add new hard tabs ('\t') at all.
Use spaces (soft tabs) instead
- in any case, configure your editor to read/write hard tabs
with width of 8 (eight)
Also:
- Avoid merge commits (unless for very good reason). Instead
use "git cherry-pick" or "git rebase" to put your commits on
top of the public branch. ref: 2a8905c93b
Also:
- jiang: please explain what you are doing, in the commit message
and on the list. Subscribe to the mailing list to receive feedback
from people for your work.
For example, what was wrong with 'parse_number'? Show a test
case and how your version fixes it (it is slower btw).
As per grischka comment, always output a space after macro concatenation
instead of trying to detect if it's necessary as the current approach
has a huge cost.
This adds parsing of (GCC compatible) visibility attribute
in order to mark selected global symbols as hidden. The generated
.o files contain hidden symbols already, the TCC linker doesn't
yet do the right thing.
Not able to generate ELF files on NetBSD yet (lacks the note and crt1.o
is actually named crt0.o on NetBSD), but -run works with these extra
defines:
-D__lint__ -D"__symbolrename(x)=asm(#x)" -D__NetBSD__
The -D__lint__ is an ugly hack, TCC should be able to emulate GCC just
fine, but it seems TCC doesn't support __builtin_va_list yet?
typedef __builtin_va_list __va_list;
/usr/include/sys/ansi.h:72: error: ';' expected (got "__va_list")
