我的gcc构建工具链生成一个.map文件。如何以图形方式显示内存映射？
这是Python中脚本的开头。它将地图文件加载到Sections和Symbols列表中（上半部分）。然后它使用HTML渲染地图（或使用sections和symbols列表做任何你想做的事情）。
您可以通过修改以下行来控制脚本：
with open('t.map') as f:
colors = ['9C9F84', 'A97D5D', 'F7DCB4', '5C755E']
total_height = 32.0
马屁2HTML.朋友
from __future__ import with_statement
import re
class Section:
def __init__(self, address, size, segment, section):
self.address = address
self.size = size
self.segment = segment
self.section = section
def __str__(self):
return self.section+""
class Symbol:
def __init__(self, address, size, file, name):
self.address = address
self.size = size
self.file = file
self.name = name
def __str__(self):
return self.name
#===============================
# Load the Sections and Symbols
#
sections = []
symbols = []
with open('t.map') as f:
in_sections = True
for line in f:
m = re.search('^([0-9A-Fx]+)\s+([0-9A-Fx]+)\s+((\[[ 0-9]+\])|\w+)\s+(.*?)\s*$', line)
if m:
if in_sections:
sections.append(Section(eval(m.group(1)), eval(m.group(2)), m.group(3), m.group(5)))
else:
symbols.append(Symbol(eval(m.group(1)), eval(m.group(2)), m.group(3), m.group(5)))
else:
if len(sections) > 0:
in_sections = False
#===============================
# Gererate the HTML File
#
colors = ['9C9F84', 'A97D5D', 'F7DCB4', '5C755E']
total_height = 32.0
segments = set()
for s in sections: segments.add(s.segment)
segment_colors = dict()
i = 0
for s in segments:
segment_colors[s] = colors[i % len(colors)]
i += 1
total_size = 0
for s in symbols:
total_size += s.size
sections.sort(lambda a,b: a.address - b.address)
symbols.sort(lambda a,b: a.address - b.address)
def section_from_address(addr):
for s in sections:
if addr >= s.address and addr < (s.address + s.size):
return s
return None
print "<html><head>"
print " <style>a { color: black; text-decoration: none; font-family:monospace }</style>"
print "<body>"
print "<table cellspacing='1px'>"
for sym in symbols:
section = section_from_address(sym.address)
height = (total_height/total_size) * sym.size
font_size = 1.0 if height > 1.0 else height
print "<tr style='background-color:#%s;height:%gem;line-height:%gem;font-size:%gem'><td style='overflow:hidden'>" % \
(segment_colors[section.segment], height, height, font_size)
print "<a href='#%s'>%s</a>" % (sym.name, sym.name)
print "</td></tr>"
print "</table>"
print "</body></html>"
这是对它输出的HTML的糟糕渲染：
我编写了一个C＃程序来显示Map文件中的信息以及通常不在地图文件中的信息（如静态符号，只要你可以使用binutils）。代码可用here。简而言之，它解析地图文件，并使用BINUTILS（如果可用）来收集更多信息。要运行它，您需要下载代码并在visual studio下运行项目，浏览到地图文件路径并单击Analyze。
注意：仅适用于GCC/LD地图文件
